Voice lets your AI Double speak in real-time conversations with visitors — using either a cloned version of your voice or a preset voice from the library. Go to Double → Voice to get started.

​
What Voice does

  • Clones your voice from an uploaded or recorded audio sample
  • Powers real-time voice conversations with visitors on any profile or embedded chatbot
  • Works alongside chat — both channels use the same knowledge, Persona, and behavior settings
  • Supports 30+ languages with automatic detection

​
Voice Types

There are two voice tiers. Both work for real-time conversations — the difference is quality and source. Note: HQ voices are marked with an HQ badge in the Voice Library. Light voices are marked LITE.

​
Choosing a Voice

You have three options:
  1. Clone your own voice — record or upload a sample and create a voice that sounds like you
  2. Pick a preset HQ voice — choose from the Voice Library (Rachel, Ryan, Sakshi, Vijay, Linda, Thomas, and more)
  3. Pick a preset Light voice — faster option for lower-latency use cases (Heart, Bella)
Click Play next to any preset to preview it before selecting.

​
Default Voice Language

Set the default language visitors start with when opening a voice chat. This is the language hint sent to speech recognition. Go to Voice → Language and select your preferred default. English (US) is set by default. Visitors see the language flag preselected in voice chat. Speech recognition will prefer that language when voice chat starts. Visitors can still switch languages manually during a conversation.

​
Expressive Mode

Toggle Expressive Mode on to add subtle, human-like expression to your Double’s voice — natural pauses, hesitation, or laughter when it fits the conversation. Makes your Double sound less robotic and more like you. Expressive Mode is off by default. Toggle it on from the Voice dashboard.

​
Multilingual Support

Your Double speaks 30+ languages — automatically. When a visitor starts a conversation, your Double detects their language and responds in the same language. No setup needed.
  • Auto detect (default) — your Double identifies the language from the visitor’s message and replies in kind
  • Manual selection — visitors can click the country language flag icon in the chat input to pick their preferred language
Supported languages: Arabic, Burmese, Chinese, Danish, Dutch, English, Finnish, French, German, Greek, Hebrew, Hindi, Indonesian, Italian, Japanese, Khmer, Korean, Lao, Malay, Norwegian, Polish, Portuguese, Russian, Spanish, Swahili, Swedish, Tagalog, Thai, Turkish, Vietnamese What to know
  • Multilingual support works for both text chat and voice calls
  • Visitors can switch languages mid-conversation
  • Voice responses are delivered in the visitor’s selected or detected language
  • The default language set in Voice settings is the starting hint — visitors can override it

​
Pronunciation

Control how your Double pronounces your name, company, and other words without changing how they appear in the chat transcript. Go to Double → Voice → Pronunciation.
  1. Your First name, Last name, and Company are automatically pulled from your profile.
  2. Enter how your First name and Last name should sound using simple phonetic spelling, for example SAH-hith or hee-MAHN-shoo.
  3. Click Preview name to hear the pronunciation.
  4. Enter how your Company name should be pronounced.
  5. Use Custom pronunciations → Manage to add pronunciations for other names, brands, acronyms, or terms.
  6. Click Save pronunciation to apply your changes.
Note: Pronunciation settings affect voice only. The original spelling is always shown in the chat transcript.
