How to make a call

Your browser connects directly to our media servers and you'll hear your assistant respond within a few seconds.

Features

• Voice selection — Access all of our curated ElevenLabs voices with different accents and styles. Preview each voice before your call.
• Barge-in — Interrupt the assistant at any time by speaking. It stops immediately and listens to your new input.
• Echo cancellation & noise suppression — Built-in audio processing keeps the conversation clear, even in noisy environments.
• Streaming speech recognition — Your speech is transcribed in real time so the assistant can start processing before you finish speaking.
