Capabilities

What Koe does

Director-grade emotional modulation

Direct nuances in tone: breath control, hesitation, whispers, intense delivery, irony, and pitch contour through natural language instructions.

Cross-lingual voice cloning

Preserves vocal identity, formant fingerprint and emotional timbre across languages and regional dialects.

Viseme-synchronized dubbing

Phoneme timing alignment matched to video mouth shapes and facial cadence for localization.

Actor likeness rights

Every synthesized voice carries an imperceptible cryptographic watermark, and its provenance is logged.

In production

Where Koe fits

Localization

Actor-preserving film dubbing

Dub episodic television and movies into international languages while retaining the original actor’s voice characteristics.

Game dialogue

Real-time branching character speech

Deliver thousands of hours of high-performance character dialogue in video games without recording bottlenecks.

Audiobooks and podcasts

Multi-voice dramatic performances

Cast an entire ensemble of distinct characters from a single manuscript with consistent chapter-to-chapter character voices.
