Klatt Voice Synthesis

Mon, 01 Jan 0001 00:00:00 +0000

The Klatt Voice Synthesis system provides custom text-to-speech for GS_Play projects using Klatt formant synthesis with full 3D spatial audio. It uses SoLoud internally for speech generation and MiniAudio for spatial positioning.

The system has two layers:

KlattVoiceSystemComponent – A singleton that manages the shared SoLoud engine instance and tracks the 3D audio listener position.
KlattVoiceComponent – A per-entity component that generates speech, queues segments, applies voice profiles, and emits spatialized audio from the entity’s position.

Voice characteristics are defined through KlattVoiceProfile assets containing frequency, speed, waveform, formant, and phoneme mapping configuration. Phoneme maps convert input text to ARPABET phonemes for the Klatt synthesizer, with support for custom pronunciation overrides.
