What Is Multi-Voice Text to Speech?
Multi-voice TTS lets you assign different AI voices to different characters or sections within a single project. Instead of one voice reading everything, each character gets their own distinct voice — like a cast of actors. Essential for audiobooks with dialogue, games with multiple characters, podcast dramatizations, and e-learning with instructor + student voices.

How Multi-Voice TTS Works in SpeechGeneration AI
Prepare Your Script
Write dialogue with character labels or section markers. Decide how many distinct voices you need — 4-8 characters is the sweet spot. Choose voice genders, accents, and tones that differentiate characters clearly.
Assign Voices Per Character
Select a different voice for each character from 95+ options. Choose quality tier per character: Economy for minor roles, Studio+ for leads. Add emotion tags for expressive delivery: [excited], [whisper], [serious].
Generate & Export
Generate each section and preview. Export individual sections as MP3 or WAV. Stitch together in your audio editor or video editor. Up to 5,000 characters per generation.
