A vocoder that synthesizes speech by modeling and resynthesizing the vocal tract's formant frequencies — the resonant peaks of the speech spectrum. Parameters: input audio signal, formant detection algorithm (e.g., linear prediction analysis), formant frequency tracks, bandwidth parameters, and amplitude envelopes for each formant band. Persistence mechanism: software implementation of the formant analysis-synthesis pipeline, typically realized through digital signal processing algorithms that extract formant parameters from speech and reconstruct them via excitation-source filtering. The output preserves the perceptual qualities of voiced speech while enabling pitch and duration control independent of the original source.

Relations from this entry
- speech-processingSERVES →
A formant vocoder synthesizes speech by modeling vocal tract resonances (formants) and serves speech processing by providing a parametric approach to speech analysis and synthesis. It is a tool used within speech processing pipelines for vocoder-based processing and analysis.
- cmspg0fzk056ijlss3ydafq7bDEPENDS_ON →
Formant vocoder extracts formant frequencies, bandwidths and excitation parameters from speech spectra per frame. Removing spectral analysis removes the input representation on which formant tracking operates, so the vocoder cannot perform analysis or synthesis.
- audio-processingSERVES →
Formant vocoder is built and maintained for the sake of audio processing: it enables creative voice synthesis, vocal timbre manipulation, and sound design in music production beyond speech processing. Its parameters (formant frequency tracks, bandwidths, excitation) are applied in audio workflows for vocal synthesis and voice conversion. Servant points at master per Law 8d. Consistent with phase-locked-vocoder's dual SERVES to audio-processing and speech-processing.
- vocoderINSTANCE_OF →
Formant vocoder is a specific implementation family within the broader vocoder technique class.
