Aristech TTS-Client for NodeJS

This is the NodeJS client implementation for the Aristech TTS-Server.

Installation

npm install @aristech-org/tts-client

Usage

import { TtsClient } from '@aristech-org/tts-client'
import fs from 'fs'

const client = new TtsClient({ host: 'tts.example.com' })
const buffer = await client.synthesize({
  text: 'Hello, world!',
  options: { voiceId: 'anne_en_GB' },
})
fs.writeFileSync('path/to/output/file.wav', buffer)

There are several examples in the examples directory:

• file.ts: Pretty much the same as the example above.
• streaming.ts: Demonstrates how to stream audio to a sox process which plays the audio as it is being streamed.
• voices.ts: Demonstrates how to get the available voices from the server.
• phoneset.ts: Demonstrates how to get the phoneset for a voice.
• transcribe.ts: Demonstrates how to get how a voice would pronounce a given word.

You can run the examples directly using tsx like this:

1. Create a .env file in the node directory:

HOST=tts.example.com
# The credentials are optional but probably required for most servers:
TOKEN=your-token
SECRET=your-secret

# The following are optional:
# ROOT_CERT=your-root-cert.pem # If the server uses a self-signed certificate
# SSL=true # Set to true if credentials are provided or if a ROOT_CERT is provided
# VOICE_ID=some-available-voice-id

2. Run the examples, e.g.:

npx tsx examples/streaming.ts
