Samtal Voice API

Voice Cloning

Record a short speech sample, then use it as the voice for TTS. Both the audio and its transcript are required.

Step 1: Record Reference

Speak naturally for 5-15 seconds. For inspiration, you could read one of these sentences (or anything else you like):

The quick brown fox jumps over the lazy dog near the riverbank on a warm summer afternoon.
I believe that technology, when used thoughtfully, can make the world a better place for everyone.
Den lilla röda stugan vid sjön är ett av mina finaste barndomsminnen från sommaren.
Jag tror att framtiden tillhör dem som vågar tänka stort och arbeta tillsammans med andra.

Step 2: Verify Transcript

Auto-filled from your recording. Edit if needed.

Step 3: Generate with Cloned Voice
