Subject: tts: account for the vocoder pass in the timings line (#26733)
X-Git-Tag: upstream/0.0.10438~112
X-Git-Url: https://git.djapps.eu/?a=commitdiff_plain;h=3653e6d6d547ec763317d9ecd0ace334a7e21359;p=pkg%2Fggml%2Fsources%2Fllama.cpp

tts: account for the vocoder pass in the timings line (#26733)

get_output runs the waveform work the pipeline defers to it, from a
single trailing window to a full pass depending on the model. Measuring
it keeps the reported total and the audio to process ratio honest.
