Voice Library

Audixa offers a diverse library of high-quality voices. This guide explains how to browse, select, and use voices in your API requests.

Voice Models

Audixa provides two model tiers:

Model	Description	Use Case
Base	Standard high-quality voices	General TTS, high volume, cost-effective
Advanced	Premium voices with cloning and emotions	Custom voices, expressive speech, dubbing

Listing Voices via API

Fetch available voices using the /voices endpoint:

# Get Base model voices
curl -X GET "https://api.audixa.ai/v3/voices?model=base" \
  -H "x-api-key: YOUR_API_KEY"

# Get Advanced model voices
curl -X GET "https://api.audixa.ai/v3/voices?model=advanced" \
  -H "x-api-key: YOUR_API_KEY"

import audixa

audixa.set_api_key("YOUR_API_KEY")

# Get Base model voices
voices = audixa.list_voices(model="base")
for voice in voices:
    print(f"{voice['name']} ({voice['voice_id']}) - {voice.get('accent', 'N/A')}")

# Get Advanced model voices
advanced_voices = audixa.list_voices(model="advanced")

import Audixa from 'audixa';

const audixa = new Audixa('YOUR_API_KEY');

// Get Base model voices
const { voices } = await audixa.getVoices({ model: 'base' });
for (const voice of voices) {
  console.log(`${voice.name} (${voice.voice_id}) - ${voice.accent ?? 'N/A'}`);
}

import Audixa from 'audixa';

const audixa = new Audixa('YOUR_API_KEY');

// Get Base model voices
const { voices } = await audixa.getVoices({ model: 'base' });
voices.forEach(voice => {
  console.log(`${voice.name} (${voice.voice_id}) - ${voice.accent || 'N/A'}`);
});

The model query parameter is optional. Use base or advanced to filter.

`name`	string	Human-friendly voice name

`accent`	string	Voice accent/language (e.g., “American”)

Using a Voice

Once you’ve selected a voice, use its voice_id in your TTS request:

{
  "text": "Hello, this is a test.",
  "voice_id": "am_ethan",
  "model": "base"
}

Make sure the model in your TTS request matches the model the voice belongs to.
