DeepSpeech Demo

About

This is a simple web-interface and Node server that uses DeepSpeech to create a local Speech-to-Text service.

I mostly built it for myself, in order to play around with DeepSpeech, but it can be used as a starting point for your own experiments.

Prerequisites

The demo relies on SoX being available on your system and in your PATH.

A quick seach for how to install SoX on (windows|ubuntu|mac) should do the trick for you if you don't know how to install it, at least it did for me.

Install

First, clone the repository:

git clone git@github.com:asciidisco/deepspeech-demo.git

Then change into the directory & perform an npm install:

npm install

As this downloads the pre-trained models from the DeepSpeech releases as a postinstall step, which are roughly 1.4 GB, it might take a while.

After that, start the server using:

npm start

And navigate to http://localhost:3000

Usage

The user interface is quite reduced, after you´ve agreed that the page is allowed to use your microphone, you just need to hit the "Listen" button and speak a few words into your microphone. After you finished your sentence, you need to hit the "Listening..." button once again, so that the recorded sound can be processed. After a few seconds, you should see the text in the result box below the button.
