pub fn read_speaker_vector(path: &Path) -> Result<Vec<f32>, FttsError>Expand description
Read a precomputed 1,024-wide speaker vector.
See the module docs on why this is a raw vector rather than a .ftvoice pack.
§Errors
FttsError::Input when the file is unreadable or is not exactly
SPEAKER_VECTOR_BYTES bytes — a truncated vector would otherwise be padded with silence and
change the voice in a way only listening could detect.
