Retrieves a transcript of a Youtube Video( FREE Version)

Transcribing a Youtube video with a given URL

WHAT DOES IT DO?

Retrieves automatically generated and/or manually uploaded transcript of a Youtube Video. Polishes raw transcript
with Spacy's en-core-web-lg-model, by inserting punctuation marks wherever necessary as well as capitalizing the start of each sentence.

IS IT ANY GOOD?

YES! Most words are grammatically correct with a very few spelling errors. However, you might see some punctuation errors such as double dots, double commas but it is bearable.Considering this is a free service, one can turn a blind eye to the occasional punctuation errors, in my opinion.

ANY RECOMMENDATIONS?

If you're looking for the best YouTube video or any kind of audio transcription, I recommend checking out AssemblyAI. It costs $0.9 per hour.

Further usages:

Translate transcript

YouTube has a feature which allows you to automatically translate subtitles. This module also makes it possible to access this feature. To do so Transcript objects provide a translate() method, which returns a new translated Transcript object:

transcript = transcript_list.find_transcript(['en'])
translated_transcript = transcript.translate('de')
print(translated_transcript.fetch())

List available transcripts

If you want to list all transcripts which are available for a given video you can call:

transcript_list = YouTubeTranscriptApi.list_transcripts(video_id)
