bobby-snips-tts

bobby-snips-tts is an implementation of snips-tts written in Node.js. Why? Because Node.js is life!

It's a part of Bobby Assistant Project but it's designed to run in standalone. So, feel free to fork, use and modify it.

This implementation can use Google Text-To-Speech (and maybe more in the future) as replacement of pico2wave for more natural speak.

Because Google TTS (and much more TTS) are Online TTS, pico2wave is used has offline or timeout failover.

Dependencies

Get Google Text-To-Speech API Key

1. Select or create a Cloud Platform project.

   Go to the projects page

2. Enable billing for your project.

   Enable billing

3. Enable the Google Cloud Text-to-Speech API.

   Enable the API

4. Set up authentication with a service account so you can access the API from your local workstation.

This guide is an exact of Official Google Text-To-Speech Project. See more on googleapis/nodejs-text-to-speech

Install LAME

LAME is used for converting MP3 buffer from Google TTS API to WAV buffer on the fly because Snips Audio Server play only WAV buffer.

bobby-snips-tts can work without LAME by asking WAV buffer directly from Google TTS API but WAVs are about 10 times bigger than MP3s so slower on network.

With apt-get LAME can be simply install by running

apt-get install lame
