Reading Aloud
Have AgentOne read messages out loud using text-to-speech.
AgentOne can read assistant messages out loud. You pick a voice provider, configure how it sounds, then tap the speaker icon on any response to hear it.
How It Works
The read aloud button appears on every assistant message when a text-to-speech provider is configured. Click it and AgentOne streams the message through your speakers. Click it again or tap the stop button to interrupt.
Reading aloud uses its own API keys and provider selection - it's separate from the provider you use for chat.
Setting It Up
- Open
Settings->Providers. - Scroll to the
Text-to-Speech Providerscard. - Choose a provider from the dropdown.
- Pick a voice model.
- Enter the provider's API key.
- Adjust the voice settings to your liking.
Once a provider and API key are saved, the speaker icon shows up on assistant messages.
Supported Providers
| Provider | What You Get |
|---|---|
| OpenAI | TTS models (tts-1, tts-1-hd, gpt-4o-mini-tts). 13 voices, speech rate, and instructions for how it should sound. |
| ElevenLabs | ElevenLabs voice models. Voice ID, speech rate, language code, stability, style, and speaker boost. |
| LMNT | Lightning-fast speech models (aurora, blizzard). Voice, language, speed, and conversational mode. |
| Hume | Expressive speech with a single model. Voice ID, speed, and instructions for how it should sound. |
Each provider needs its own API key, stored the same way as chat provider keys.
Voice Settings
The options available depend on which provider you pick:
- Speech Rate - how fast the voice reads. Available on all providers.
- Voice - which voice to use. OpenAI has a preset list; ElevenLabs, LMNT, and Hume use voice IDs from their platforms.
- Instructions (OpenAI, Hume) - tell the voice how to sound, like "Speak casually" or "Emphasize technical terms."
- Stability / Style / Voice Match (ElevenLabs) - fine-tune the delivery.
Using It
Once configured, hover over any assistant message and click the speaker icon. The icon changes to a stop button while audio is playing. Click it again to stop.
Reading aloud stops automatically when the message finishes. You can start reading a different message while another is playing - it stops the first one and starts the new one.
