Fine-Tuning Speech in the API: Pauses, Stress, Emotions

HancVoice has no SSML markup — expressiveness is controlled by clear parameters of the /api/v1/tts request and by the editor's tools.

Core parameters

• instruct — emotion and manner (in English, e.g. "calm, friendly").
• emotion — a recorded emotion of a studio voice (joyful, sad, serious…).
• speed and gain_db — pace and volume.
• eq — timbre by frequency band; effect — a sound preset (podcast, audiobook…).

Pauses and stress

Pauses and emphasis are placed in the editor (the "How to read" panel) — they are saved as segments and passed to synthesis element by element. Stress is set reliably by marking the stressed vowel in a word.

A pause in the right place changes the meaning of a phrase more than the choice of voice.
