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’s voice agent pronounces your name and company — without changing what visitors see in the chat transcript. Go to Voice → Pronunciation to set it up.
  1. Select your Profile from the dropdown
  2. Enter your First name and Last name as they appear on your profile
  3. Enter your Company on Hero card
  4. In First name pronunciation (IPA), type how your first name should sound (e.g. “Ma-axe”)
  5. In Last name pronunciation (IPA), type how your last name should sound (e.g. “Pay-ain”)
  6. In Company pronunciation (IPA), type how your company name should sound (e.g. gu:gəl)
  7. Click Generate pronunciation to preview, or Save pronunciation to apply
Note: IPA fields control the voice only. The transcript always displays your name and company exactly as entered on your profile. Tips for a good voice clone
  • Avoid noisy environments — background sounds interfere with recording quality
  • Use a good microphone — a studio mic works best; on phones, use Voice Memos (iOS) or Dolby On (Android)
  • Finish sentences naturally — avoid cutting off words or stopping mid-sentence
