I wonder if you could train some machine learning model using the data from SponsorBlock and achieve good results on podcasts as well. That way you wouldn't be dependent on a crowdsourced online database for your offline listening. Alternatively, even creating a transscript using something like [1] and scanning for words like "sponsor", "ad" or specific company names might already be a good enough heuristic.

They might be interested in integrating Vosk, it's a speech-to-text engine that is just a shared library (.so file on Linux) and comes with API support for a variety of languages: https://alphacephei.com/vosk/ https://github.com/alphacep/vosk-api Still, I've found that the Big players have much better recognition models, and the post-processing that I assume they do (grammatical, maybe syntactical inferences that improve the end result) are probably much more powerful too.

The package that this project is built on (vosk-api) mentions & includes some examples to demonstrate exactly that type of use case with ffmpeg: "...continuous large vocabulary transcription, zero-latency response with streaming API, reconfigurable vocabulary and speaker identification ... can also create subtitles for movies, transcription for lectures and interviews." * https://github.com/alphacep/vosk-api/blob/master/python/exam... * https://github.com/alphacep/vosk-api/blob/master/python/exam... * https://github.com/alphacep/vosk-api/blob/master/python/exam... (Edit: Also, thanks for introducing me to "libretranslate", looks like an interesting project.)

Yeah, I was really impressed with the project when I encountered it last year when trying out a bunch of FLOSS Speech-To-Text options. It was significantly better than the other FLOSS options I looked at--both in terms of getting it going initially & the quality of the speech to text results. I tested it with a lightly modified version of this example script: https://github.com/alphacep/vosk-api/blob/master/python/exam... What I found particularly interesting was when you have the "partial" recognition output shown in real-time you get to see how--at the end of a sentence--it may change a word earlier in the sentence in the final recognition output based on (I guess) the additional context of the full sentence. (I just did a quick test again (with the installs from my testing last year) using an internal laptop microphone & the test scrip

t recognized a significant chunk of my speech (using a headset definitely improves things though) whereas with the same environment a test with `mic_vad_streaming` (from `DeepSpeech-examples-r0.9` with `deepspeech-0.9.0-models.pbmm`) failed to recognize any words at all.)
