Voice Library

Audixa exposes a catalog of system and account-owned voices. This guide explains how to list voices, check model compatibility, and use a voice_id in an API request.

Voice Models

Audixa provides two model tiers:

Model	Description	Use Case
Base	Voices compatible with `model: "base"`	Supports the `speed` delivery control
Advanced	Voices compatible with `model: "advanced"`	Supports `cfg_weight` and `exaggeration`

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 requests

response = requests.get(
    "https://api.audixa.ai/v3/voices",
    headers={"X-API-Key": "YOUR_API_KEY"},
    params={"model": "base"},
    timeout=30,
)
response.raise_for_status()

for voice in response.json()["voices"]:
    print(f"{voice['name']} ({voice['voice_id']}) - {voice.get('accent', 'N/A')}")

const query = new URLSearchParams({ model: 'base' });
const response = await fetch(`https://api.audixa.ai/v3/voices?${query}`, {
  headers: { 'X-API-Key': 'YOUR_API_KEY' }
});
if (!response.ok) throw new Error(await response.text());

const { voices } = await response.json();
for (const voice of voices) {
  console.log(`${voice.name} (${voice.voice_id}) - ${voice.accent ?? 'N/A'}`);
}

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

}

Voice Properties

Each voice object includes:

Property	Type	Description
`voice_id`	string	Unique identifier to use in `/tts` requests
`name`	string	Human-friendly voice name
`gender`	string	`Male` or `Female`
`accent`	string	Voice accent/language (e.g., “American”)
`description`	string	Brief description of voice characteristics
`free`	boolean	Internal voice-access classification used by plan rules; it does not make generation free
`is_custom`	boolean	Whether this is your custom voice

Using a Voice

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

{
  "text": "Hello, this example contains enough text for a generation.",
  "voice_id": "am_ethan",
  "model": "base",
  "audio_format": "mp3"
}

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

Custom Voices (Advanced Model)

With the Advanced model, you can:

Clone Your Voice

Create a custom voice from audio samples.

Adjust Emotions

Control emotional tone via exaggeration and cfg_weight.

Fine-tune Settings

Adjust expressiveness for creativity control.

Branded Voices

Create unique voices for your brand.

Custom voices appear in your /voices?model=advanced response with is_custom: true.

Voice Selection Tips

Match your audience: Choose accents that resonate with your target users
Consider context: Professional content may need authoritative voices; casual content benefits from friendly tones
Preview first: Compare the fixed samples at audixa.ai/voices before purchasing
Validate compatibility: Use the model returned with each voice instead of guessing
