Read Prompts and Submit Recordings

Before you Begin Recording Prompts

Turn off any other audio programs on your PC (i.e. music players, audio editors, etc.)

Position your mike so it does not pick up your breathing.  While recording, try to minimize any non-speech noises (i.e. lip smacking, taking a breath, ...) or background noise.  Don't exhale until after you have clicked the Stop button. 

The black box near the bottom of your screen will display the audio waveform of your recording. Please record a test recording to ensure your microphone volume is not too high or too low.

Recording Prompts 

For each prompt line, please record your speech as follows:

  1. click the Record button,
  2. pause for half a second,
  3. Read the corresponding prompt sentence,
  4. pause for half a second, and then
  5. click the the Stop button.
If you make a mistake, click Record again to re-record your prompt.

Once you have completed recording all ten prompts the Upload button will activate.  Click the Upload button to upload your entire submission to the VoxForge repository as a single zip file.

Repeat the process (multiple submissions are encouraged!)  

Other Options for Submitting Speech

using the Audacity audio editor;

using your telephone.

The VoxForge Speech Submission Applet should appear here. Please see the VoxForge Java Troubleshooting Guide to determine if you have Java installed on your PC - this is required in order to use the audio recorder.

Firefox on Linux \w Sound Emitting Flash Controls
By Dominic - 4/26/2008 - 1 Replies

I had the same problem as the poster above. This problem happens in Firefox on Linux if you have a flash component in one of the browsers other tabs that causes firefox to grab control of the soundcard, so that Java is unable to get exclusive access to the card when it needs it (Java does not go via firefox).

Essentially the problem is that niether firefox nor Java connect via ALSA which allows all applications to connect at the same time, but try to take control of the raw sound device themselves. This is what I see when I run the lsof command to see which applications are using the sound devices:

 

root@dominic-laptop:/etc# lsof | grep snd
mixer_app  5578    dominic   19u      CHR     116,10                14218 /dev/snd/controlC0
totem     30649    dominic   17u      CHR     116,10                14218 /dev/snd/controlC0
firefox-b 30797    dominic  mem       CHR      116,8                14183 /dev/snd/pcmC0D0p
firefox-b 30797    dominic   44r      CHR      116,2                13897 /dev/snd/timer
firefox-b 30797    dominic   49u      CHR      116,8                14183 /dev/snd/pcmC0D0p

 

As you can see, whereas totem and mixer_app connect via ALSA (controlCO) at the same time, firefox connects directly to the raw sound device (pcm...) and so prevents Java. This problem goes away by closing the tabs that have sound producing flash controls.

playback of recorded prompts fails

Robin said (from this post):

A new Dutch 'speech submitter' tried to playback the prompts he recorded using the Java submission app. He got this error:

unable to open the line: javax.sound.sampled.LineUnavailableException: Audio Device Unavailable

He posted a screenshot here:
