@aristech-org/stt-client

Aristech STT-Client for NodeJS

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

Installation

npm install @aristech-org/stt-client

Usage

import { SttClient } from '@aristech-org/stt-client'

const client = new SttClient({
  apiKey: process.env['ARISTECH_STT_API_KEY'], // This is the default and can be omitted
})
const results = await client.recognizeFile('path/to/audio/file.wav')
console.log(results.map(r => r.chunks[0].alternatives[0].text).join('\n'))

There are several examples in the examples directory:

• recognize.ts: Pretty much the same as the example above.
• streaming.ts: Demonstrates how to stream audio to the server while receiving interim results.
• models.ts: Demonstrates how to get the available models from the server.
• nlpFunctions.ts: Demonstrates how to list the configured NLP-Servers and the coresponding functions.
• nlpProcess.ts: Demonstrates how to perform NLP processing on a text by using the STT-Server as a proxy.
• account.ts: Demonstrates how to retrieve the account information from the server.

To run the examples, use npx tsx. For example:

npx tsx examples/streaming.ts

API Key

If you didn't get an API key but a token, secret and host, you can generate an API key with our API key generator.

Alternatively you can still provide the connection options manually.

import { SttClient } from '@aristech-org/stt-client'

const client = new SttClient({
  host: 'stt.example.com:443',
  auth: {
    token: 'your-token',
    secret: 'your-secret'
  }
})
