Deep-speech react app to test trained models,to visualize the speech to text process, to record the audio from mic to wav using the webaudio API, or to create/use a custom open speech-to-text API.

Live Demo.

git clone https://github.com/buddyeorl/deep-talk.git

This app needs two files to work, the acoustic model: deepspeech-0.8.2-models.pbmm

and the following scorer: deepspeech-0.8.2-models.scorer

download both files to /server/index/

In the terminal in the repo root directory npm run build .

Now in the terminal cd server && node server.js

*** defaults to http://localhost:3001 ***

API calls to

https://deep-talk.azurewebsites.net/api/v1/getVoice

POST requests accepts 16kHZ mono 16bits WAV audio files in multipart form data,the field name should be 'audio'

sample responses:

No audio file:

{
    "message": "No audio file has been received"
}

No recognition:

{
    "error": "No speech was recognized"
}

Success:

{
    "message": "success",
    "data": "two three"
}

Please note that the app resamples the audio recorded to 16kHZ mono 16bits(as used when training the model), I might add different samplerates recording options if requested.

Also note that this app will recognize pauses in speech and trimm the audio files and speech recognition responses accordingly.
