Does such a software exist?

If I had one file, I wouldn't have asked. I have at least 100 files, and have heard them once at least, and would like to find whether certain keywords occur in them. Something like batch-processing is what I an looking for. That's why I asked.
Fur enuff :-D

use a text to speech tool that generates .VTT close captioning files. Each snippet of a few words will have a timestamp to indicate when it's displayed. Azure has an API for it, and I think AWS has recently upgraded their video to text processing tools to offer the same.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason?

To get a feeling for how reliable such systems are, get yourself a YouTube account so that you can upload a few files there, and play them back selecting 'Auto generated' subtitles. A few years ago, that function tried to autogenerate subtitles even from instrumental music, which could lead to some really funny results. Today, it just says [music], if it cannot detect any vocal part. For vocal music, it quite often misinterprets. For speech, it is surprisingly good, as long as the background noise level is low, the speech is distinct and only one person at a time is speaking. For English only, of course. (I assume that those who really put resources into this kind of stuff also has high performance versions for Russian speech, but don't expect that to be released to the civilian society :-).)

I'm well aware of the limitations in computerized speech to text. The versions offered as services by the big tech companies are the least bad ones available though. I've never looked into generating non-english transcripts/captions.

I have an MP3 file. It is an hour-long lecture on a topic about weather. I would like to find out ('seek') the exact time(s) when the word 'rainy' gets played in this MP3 file, without listening to the entire hour-long lecture. Similar to finding a substring in a long string, but finding an audio clip within an audio file. Does such a software functionality exist? My Google search didn't yield much.

assuming you don't have a life ;) what a great research project. Me? I just want to learn how to hang interior doors square, but we all have our goals.

Surely there should be something invariant between these two utterances of 'rainy'.
Yes and no. The similarities can be washed out by the noise in the sentence, particularly with all of the different accents/varieties of English that are spoken around the world. Also, just identifying word endings can be tricky. Picking out words from "rainy days" can give "rainy days", "ray knee days" or "ray need as'" without changing the sound.

Run the files through a (batch) speech recognition program and dump the whole thing to a text file. You can (re)search the text without having to go back to the mp3. Looking at a file in its entirety will help in deciding how to "train" the (ML) process.

The answer in that link leads to the VOSK project[^], which in turn has a page that lists several projects that integrate the VOSK toolkit. One of those projects is pretty much exactly what the OP is asking for: mp4grep[^]. Looks like it's Linux-only, and using it is a two-step process unless you happen to be starting with a 16khz wav file, but it appears to automate the process of using speech recognition to generate a timestamped transcript, and then grep'ing the result to find the word or expression of interest. I didn't actually try to use it, so I can't vouch for its quality, but it looks pretty neat if it works!

Hmmm, Did you find a solution for this? [Whisper](https://openai.com/blog/whisper/) was released just yesterday. [GitHub - OpenAI/whisper](https://github.com/openai/whisper) Looks really easy to use.

Thanks a lot. Will download and take a look.
