Auto generate subtitles?
Happy scribe, I know, Steve has used. I've tried the free trial of it and it is pretty sweet. It has a good editor too and identifies where it things it might be wrong with its transcription. Not particularly cheap though. For myself, with plenty of German content I've decided not to use it, but if I didn't have a good content I would probably use it.
I listed otter.ai as well. It's a competitor. It looks to be cheaper so it could be another option. I've not used it at all though, so I can't comment on how it compares to happy scribe.
Regarding transcription services: I have shared some of my experiences in this (unwieldy) thread:
Basically all the "Big Tech" companies have some sort of speech recognition software. And after having tried a few, I find them all to be basically excellent, at least for major languages like Mandarin Chinese, French, English etc. For more exotic languages like Romanian the results were worse but usable. For me it basically comes down to convenience, some of these services like Microsoft Azure and wit.ai seem to be geared toward developers who want to bring speech recognition to their apps or IOT devices, so short sound snippet are often expected. Users are expected to have a basic level of programming / scripting skills to interact with the APIs. AWS on the other hand seems to have considered longer form audio and provides a convenient web interface, so I use that. Pricing is comparable across the board, but depends on region and currency obviously.
Regarding smaller ventures like happyscibe and sonic.ai, I feel a bit hesitant, they are really pricey in comparison to "Big Tech". Also I have read (1) that the quality of a speech recognition system basically hinges upon the amount of training data, so I don't really get how these smaller firms can even compete with Alexa, Siri, Google Now!...
I would, by the way love I LingQ could implement an interface to AWS, they already use it extensively.
So you could just drop in an audio file to LingQ, it would be processed and, 10 minutes later a LingQ lesson would be created, audio and text being synchronized with timestamps. Technically this seems feasible, the problem might be the payment, this would have to be billed separately, I would think.
Thanks Bamboozled. I think I dropped out of reading that thread once it got too long for me to follow. I'll be curious to try the couple of suggestions you made as I hadn't found these before.
No, LingQ can't generate subtitles, sorry.
