Subject description: V3 adds more visually impaired features to webcam & voice control.
 

The latest version of Obedient Pup (V3) released 5th November 2013 starts here:
www.murga-linux.com/puppy/viewtopic.php?p=734866#734866

A brief overview of V3 can be seen here: http://tinyurl.com/oyubbtq


Fri 16 Aug 2013 (V1)
Whilst primarily intended as an accessibility Pup for the severely disabled, it is also suitable for anyone who wishes to try or use these methods of control.
It is based on MouseCam Pup V6, which itself was a re-master of Precise Puppy 5.6.1 (k 3.3.44). Existing users of MouseCam Pup for whom voice is also an option, will benefit from its features and should be able to mix the two methods of control to great effect as it eliminates the need for typing. If you have used neither before, I would recommend becoming familiar with each method separately before attempting to combine the two.

The features of MouseCam Pup are well documented in its own thread so I will not repeat them here. Minor changes from the point of view of a pure Eviacam user are:
1. Text to speech (TTS) now included by default.
2. Navigation icons removed from across top of screen.

The main voice control features include:

1. The ability to search for and play anything on YouTube.
2. Send and receive voice mail using the Vocaroo service.
3. Use the new Google voice search with some spoken replies when Google provides them.
4. To open any website.
5. To open and navigate any hyperlinks on the BBC News site. (The ability to navigate webpage hyperlinks by voice is site dependant. It works on some but not others.)
6. Desktop and webpage navigation.
7. Integration with “single switch” solutions.
8. Experimental XBMC navigation.

Background notes:

Briefly the voice control side of things is based on the “Palaver” project which is under heavy development and has not yet progressed to a release. Much has been discarded or modified to work with Puppy and there are a host of additional scripts. As it stands, that project has two basic operating methods plus a dictation mode which I disabled as dictation is already sorted and in the light of the inclusion of voice mail is pretty much redundant.
Their first operating method is to press a hotkey, speak and then press the hotkey again to stop the recording and send the resulting flac file to the Google speech API site for analysis. The second method is “continuous listening” where recording starts and stops as the ambient sound level rises and falls when someone speaks.
I have opted for an entirely different approach, more akin to Google’s voice search, where a single press of the hotkey gives about 7 seconds worth of recording. This is more than enough for command or search purposes. It also means that you can use speakers or headphones.

The Google speech API is very good, often being able to work out from the context what was said. An example: If you said “close” that might be heard as “close” or “clothes”. If however you said “close window” Google would likely get it correct from the context. This intelligence can however be a problem with voice commands where you do not want your words to be mistaken or interpreted. The aim is to get it to return exactly what you said so that scripts can be triggered. In tests I also noted that it can struggle with certain words such as “up”, “max” and “maximise”. If some of the command words that I have chosen seem a little odd it is because I have gone for words with the best recognition factor. Palaver also employs fuzzy recognition logic to improve matters further. An example:
Suppose you said “send voice mail”. Google might return precisely that or “send voicemail” or even “send voice mails”. Fuzzy recognition is used to allow for any of those three possibilities so that the command word or words still trigger the correct action. One last thing to mention in this section is that a command word or words can be followed by a string of non command words that will be input as say a site to go to or something to be input to a search field. Enough of the technical stuff!

Where to obtain the ISO: (345 MB)

The ISO and MD5 are to be found here:
http://mydrive.ch (Switzerland)
Guest login name = maddog@puppy4
Password= maddog

And on: (When I can login and upload it-Edit 17/08/2013-Now available)
http://www.puppylinuxstuff.meownplanet.net/ETP/ (Australia)

Setup Procedure:

1. Complete the normal "first-run" dialogues then reboot and create a 768 MEG Ext4 savefile.

2. If you are using an LCD display, launch Fontwizard from the JWM/desktop menu, tick all boxes & then click on apply. Restart X.

3. Launch Gmail via Chrome and setup an account if you do not already possess one. Log in and ensure that you tick the box to stay signed in. Setup a contact in Gmail named “Self” with your own Gmail address. (This will be used later for testing voice mail)
Close the browser but do not log off Gmail.

4. Click the speaker icon at the right hand end of the taskbar at the bottom of the screen and set the volume at 50%.

Hotkeys for voice search /control:

There are 3 options:
1. Left hand windows key. (Preferred method)

2. For Eviacam users, hotkey icons on both the desktop and the navigation sidebar.
(Reminder – The scroll lock key toggles webcam control on and off once launched)

3. Pause/break key for use with a single switch.

Walk-Through: (Key command words are capitalised)

Leaving the hotkey alone for the moment and just using the mouse, we will use the desktop Dictate icon to demonstrate TTS and to adjust speaker/headphone level.
We will then use it to confirm and adjust microphone operation with some dictation.
Start by clicking the desktop “Dictate” icon. After a few seconds you should hear audio. Close the window by clicking the close icon on the sidebar then repeat a few times. Between repetitions adjust your volume level.

With the dictation window open and the lines of text visible, click on the last line and edit it to something that you would like the orator to say to you. Highlight what you have typed, then from the right click menu pick “Speak Text”.
Play with this for a while being as creative as you like.
Once satiated, click on the “Clear Canvas” button. Exit and re-launch Dictate to try out the dictation mode. You may need to adjust your microphone level to get decent results.

Still just using the mouse, let’s explore the new Google Voice Search by clicking the red sidebar search icon. (We will launch it later by voice command)
When invited to speak try the following:
“Obahma”
Click the side bar search icon again and try
“Weather New York”
Click again & try
“Time in Sydney”
Click again & try
“Six times twelve”
Click again & try
“How tall is the Eiffel Tower?”
Click again & try
“Who am I”

If it gets all these correct, your mike is fine for voice control and you can continue. If not, your mike needs further adjustment as voice control uses the same service.

Voice Control-Search:
With a clear desktop and nothing running:

[Tap the HOTKEY and say] “VOICE SEARCH”

Repeat the above test just using voice commands.
You can close the window between searches if you wish by issuing:

[Tap the HOTKEY and say] “CLOSE WINDOW”

Voice Control-YouTube:
With a clear desktop and nothing running:

[Tap the HOTKEY and say] “YOUTUBE James Taylor”

Too quiet?

[Tap the HOTKEY and say] “INCREASE VOLUME”

Too loud?

[Tap the HOTKEY and say] “DECREASE VOLUME”

These commands work in 12% increments and may be repeated. With one exception, the window must be closed between YouTube searches.

[Tap the HOTKEY and say] “CLOSE WINDOW”

Now for another search.

[Tap the HOTKEY and say] “YOUTUBE Queen Live Aid”

(You may need to decrease volume – if so, don’t forget to press the hotkey first.)

[Tap the HOTKEY and say] “CLOSE WINDOW”

Another search.

[Tap the HOTKEY and say] “YOUTUBE Elephant plays in pool”

Want to move to the next video?

[Tap the HOTKEY and say] “GO DOWN”

Changed your mind?

[Tap the HOTKEY and say] “GO UP”

Fancy a break?

[Tap the HOTKEY and say] “COFFEE”

Back already?

[Tap the HOTKEY and say] “RESUME”

[Tap the HOTKEY and say] “CLOSE WINDOW”

One last search.

[Tap the HOTKEY and say] “YOUTUBE Simon and Garfunkel the Sound of Silence”

I mentioned one exception to the need to close the window between YouTube searches. So with S&G playing:

[Tap the HOTKEY and say] “GO TO news dot sky dot com”

Use this for background music whilst you browse.

[Tap the HOTKEY and say] “CLOSE WINDOW”

Voice Control - BBC News:
With a clear desktop and nothing running:

[Tap the HOTKEY and say] “NEWS”

You should be taken to the BBC World News page upon which there will be many hyperlinks to stories and videos.
Suppose you see the following link and wish to visit it:

“Australian rivals face off in debate” There are 4 possible options here.

[Tap the HOTKEY and say] “THE Australian”

[Tap the HOTKEY and say] “THE rivals”

[Tap the HOTKEY and say] “THE face”

[Tap the HOTKEY and say] “THE debate”

If you used the first one, providing there was no hyperlink further up the page containing the word “Australian” you will be taken to that link after a short wobble!
If there were such a hyperlink further up the page you would be taken to that. If you happened to spot the fact that there were multiple links on the page containing the word “Australian” but none containing the word “debate”, issue that instead.

Try to use a word in conjunction with THE (The command word) that makes sense and will not be interpreted by Google. You would not for example use “THE in” as Google might return “The Inn” and “in” would be a common word anyway.

Sometimes you will only have one option as nothing else makes sense or could be interpreted.
Suppose you wanted to visit the link “Bossa Nova' singer Eydie Gorme dies”
The only sensible option would be:

[Tap the HOTKEY and say] “THE singer”

This sounds complex but soon becomes second nature. To assist I have arranged to briefly display on screen the word that Google thought you said which can help if it got it wrong and you go to an unexpected link.

Please note also that all the links on the bars at the top of the page are available for navigation. So you could for example use:

[Tap the HOTKEY and say] “THE technology”
Or
[Tap the HOTKEY and say] “THE weather”

Many of the hyperlinks lead to videos which frequently start playing automatically.
If one does not, the following command may persuade it to start. If it fails move on, nothing to see here!

[Tap the HOTKEY and say] “PLAY”

Other relevant voice commands:

[Tap the HOTKEY and say] “PAGE DOWN”

[Tap the HOTKEY and say] “PAGE BACK”

[Tap the HOTKEY and say] “MAXIMUS” (Maximise active window)

[Tap the HOTKEY and say] “RESTORE” (Restore active window to original size)

[Tap the HOTKEY and say] “MINIMUS” - This is only for Eviacam users as the window cannot be raised with voice control.

[Tap the HOTKEY and say] “PREVIOUS” (Previous webpage if applicable)

[Tap the HOTKEY and say] “NEXT” (Next webpage if applicable)

Voice Control – Send Voice Mail:
With a clear desktop and nothing running:

[Tap the HOTKEY and say] “SEND VOICE MAIL”

Vocaroo will launch together with a pop up message with black text on a yellow background. When that message vanishes a 30 second recording period will commence. At the end of that period a Gmail compose window will appear containing the hyperlink to the recording ready for you to address.

[Tap the HOTKEY and say] “SEND TO Self”

[Tap the HOTKEY and say] “POST”

A screen message will then confirm that it has been sent and all windows will close.

[Tap the HOTKEY and say] “OPEN Google Chrome”

A message should pop up confirming that you have sent yourself a voice-mail.

Want to hear your voice mail?

[Tap the HOTKEY and say] “OPEN MAIL”

This triggers a procedure that searches for unread mail and opens the latest unread mail. It then gives the hyperlink within the body of the mail keyboard focus and halts.
This gives you the chance to inspect the link and to satisfy yourself that it is a link to a recording on Vocaroo.com. It would be highly dangerous to fully automate the opening of a link in what might be an unsolicited mail. Once there is no unread mail it will fall back to just displaying read mails.

If you are happy, issue the following command to listen to the message.

[Tap the HOTKEY and say] “COFFEE”

Once it has played.

[Tap the HOTKEY and say] “CLOSE WINDOW”

To send to multiple recipients repeat the “SEND TO” command before posting. If Google gets the last entered name wrong, simply remove it with the following command:

[Tap the HOTKEY and say] “REMOVE”

Note that you only need to say the first name but that Google can struggle with names and will input what it believes it has heard even when the name is not in your contacts.
Names such as FRED or JOHN will probably not be a problem but something like ALEXANDROS might be an issue. The quick fix for this is simply to rename the contact to something that the Google voice API does consistently return correctly. ALEX for example.
You may opt for a nick name. To test out what Google is likely to return, use voice search on it several times to see what reliability you get. (That is what I did to determine reliable command words.)

Group names such as TENNIS CLUB, containing all your relevant contacts should be easy to rename if they are problematic.

Please note also that the 30 second period was selected primarily for reliability and is also probably the average duration of a typical answer machine message. If you need to say more, just send a second message. If you are desperate for a longer period send me a PM for instructions on how to change it. It is intended that only voice mails recorded on Vocaroo be sent to Obedient Pup users. As such the body of the email will only contain a single hyperlink to the recording on Vocaroo.com. That site can be book-marked in any browser.

Voice Control – XBMC:
With a clear desktop and nothing running:

This is experimental and subject to feedback, but given that XBMC is included, it would have been a pity not to have installed a couple of add-ons and to have tried to call them up by voice command. They can be accessed manually via the desktop icon for pure Eviacam and mouse users. You will find them when you click the favourites icon at the bottom left. There are two add-ons.
The first of these gives access to hundreds of streamed Apple iTunes trailers.
The second gives access to streamed live UK BBC TV channels plus all BBC local & national radio channels. This technically requires a UK TV license. However if you are a license holder abroad on holiday you will be familiar with how to setup XBMC access via a UK proxy server. Google is your friend in this respect Wink and I understand that many (License holding!) ex-pats make good use of this method.

The quality is, in my view, almost on a par with my DVB-T pci tuner and better than the BBC iPlayer.

Navigation within XBMC is provided by the following commands:

[Tap the HOTKEY and say] “GO DOWN”
[Tap the HOTKEY and say] “GO UP”
[Tap the HOTKEY and say] “GO LEFT”
[Tap the HOTKEY and say] “GO RIGHT”
(i.e. the four arrow keys)- Plus
[Tap the HOTKEY and say] “ESCAPE” (i.e. the Esc key)
[Tap the HOTKEY and say] “PAGE DOWN”
[Tap the HOTKEY and say] “PAGE BACK”
[Tap the HOTKEY and say] “COFFEE” (This issues the enter key)

N/B There is nothing fancy about these eight commands. They simply issue the keyboard command. They can therefore be used globally, not just in XBMC.

[Tap the HOTKEY and say] “XBMC”

To shut XBMC down correctly you must use the following command rather than closing the window.

[Tap the HOTKEY and say] “CLOSE XBMC”

This will close it cleanly and prevent problems upon re-launch.

Other Global Commands: (Precede with hotkey and follow with words or address)

MEMO
This will input any following words into just about any form, field, search or omni-box that has keyboard focus. It will then issue a hard return.

GOTO
Used to visit websites.
e.g.
[Tap the HOTKEY and say] “GOTO cnn dot com”

Final Thoughts:
A copy of this post is attached so that you may print it out for reference and use it to step through the walk-through.

All of this requires a working microphone and internet connection.

Voice recognition is not yet perfect, so be prepared to have to repeat commands.

This post due to its format has been long which implies complexity. The voice control is however very simple to use and does not take long to get used to. Rather than have a vast number of commands, I have stuck to using the bare minimum in an attempt to make it user friendly for disabled users possibly new to computing.

Thanks go to mikeslr for his great find in the form of the Google extension DeadMouse Plus 0.0.2 which is used for hyperlink navigation and to BarryK for
Precise 5.6.1. The main accolades here go to James McClain the author of Palaver.

Please see greengeek’s thread for suitable single switch solutions.

Site permissions for pepper flash and the various Google extensions used have been preset as have cookies. This should avoid being constantly asked to allow or deny Google and Vocaroo permission to use the microphone. Do not change these or clear the cookies for any of the Chrome extensions.

PostPosted: Fri 16 Aug 2013, 11:27    Post subject: Obedient Pup (V1 Released 16th August 2013)  

Reserved for Additional info, tips & FAQ

1. How to change the default "NEWS" site. (All versions)
www.murga-linux.com/puppy/viewtopic.php?p=722640#722640

2. Teaching Obedient Pup to greet you on startup. (V1 Only)
www.murga-linux.com/puppy/viewtopic.php?p=722648#722648

3. N/B Voice hyperlink navigation needs to be enabled on a per site basis. If for example you visit news.sky.com and wish to use it and permanently enable it for that site, press ctrl+shift+k whilst on that site.

4. It may seem counter intuitive but a lower microphone volume can actually benefit voice recognition. The receiving server can boost an undistorted low volume but cannot cope with the digital distortion that too loud a recording can provoke.

5. A screen resolution in the range 1280x1024 to 1920x1080 is recommended for Obedient Pup.

6. When using Obedient to send voice mail take care not to move your mouse.

Hi Ted,
No. It is just an ordinary ISO,

Darn, only one laptop and one flash with puppy available If I mess up the install of Obedient Pup I would be off line...

I am so enjoying highspeed internet at the home I'm house sitting.. Obedient PUP downloaded quickly and checksums are good.

Hi ETP -

does it have to be an EXT4 savefile? Is that a fixed requirement? (no specific reason for asking - but I've never used EXT4 so far, mostly EXT2)

Hi greengeek,
EXT2 will be fine. Ext4 is supposedly more robust in the event of a freeze or power failure, hence my recommendation.

This is a far-reaching contribution that the community will welcome. What appears here is the makings for a system that we can talk to and tell it what to do for our needs. This contribution is a significant step for all of us and for Linux in general.

@ETP ths may be what we can all be using in the not to distant future; namely a system we can vocally instruct to carry out utility needs. "Turn on the Lights", "start the stereo", "take a letter", "make a text file", "connect to the NAS and burn Obedient PUP ISO to DVD drive 2". "call my daughter", "do an internet search for ...", etc.

And, we may just get there, fully, before Android.

Klaus Knopper has been looking at Linux as a vehicle for such things where a non-sighted person can have the system function to their needs, vocally.

This is the Puppy expansion of voice operations for community users.

I hope many of us can get behind @ETP as he is doing a very good development which is equally useful to non-sighted people as well as the rest of us who are sighted. Vocal development has a lot of upside for many.

Questions:
  • Should a statement be made plain of which x86 platforms this distro would be easily at home with?
  • Can anyone of us who test, share what we did as initial tests and use of this distro?
This may be helpful for ideas of community members to ease their start-up.

Working on the 64bit version, with an eye toward ARM

Was showing off some of the efforts to a speech dr. she wanted a how-to-manual, which I laughed its under heavy development still waiting for the dust to clear. Manuals, we no need stinking manuals.... Twisted Evil

Please keep notes on confusing stuff..

Ive previously built espeak for text to speech, but I keep meaning to build pocket sphinx again for speech recognition (last time I built it, I found the interface to be too complicated to use as is - I need to simplify it for the masses) anyone know of a better option?

I've never found a V2T program on linux that works as well as Sphinx. On the flip side the only implentation that seems to work fairly well are the ones on android which actually use the Google API for the actual conversion. Not sure if someone has coded a V2T with the Google API for the linux desktop.

Hi All,

Just to clarify matters here whilst “Espeak” is used in Palaver it is not in this Pup having been dropped in favour of Ispeech’s “Select and Speak”.

Reliance is therefore placed solely on the Google APIs for both TTS and STT. The negative aspect of this is the dependency on an internet connection. The positive side is quality far exceeding Espeak, Julius, Simon & CMU Sphinx.
