the vocal synthesis module is a loosely organized collection of tools for performing [vocal-synthesis] and transforming speech/singing.
Currently, the only implemented module is a Wasm port of [sinsy] which supports uploading [musicxml] and [htsvoice] files and generating an output wav file in the browser as output.
I plan to add support for voice autotune and possibly other effects via the [world-vocoder] which has a Wasm port already in existence. Ideally, it could be implemented in a streaming fashion where [fundamental-frequency-estimation] is performed in realtime on incoming speech signals, making it able to be connected to and modulated via the [patch-network]. However, no work or planning has started for this yet.
