YouTube"s Automatic Captioning (Free)Creating subtitles with YouTube is easy, automatic transcription is built directly into the service, và can be edited in the Video Manager. Although the service does seem to be continually improving, YouTube"s transcription is notoriously (and sometimes hilariously) imperfect. Thankfully, you have the option lớn manually adjust them.
How khổng lồ Correct the Automatic Subtitles on YouTube
Select the Subtitles và CC option khổng lồ view the subtitle settings, và then click on the subtitle file you want to alter. In my case, that is English (Automatic).

Watson + Amara (Free/Paid)
You might have heard about IBM"s Watson supercomputer when it was defeating defending Jeopardy! champions in 2011. IBM have put Watson giải pháp công nghệ to use processing all kinds of data, including speech. Simply upload an audio file to the speech-to-text demo & it will transcribe the audio for you.
Go ahead and jump to the app. Don"t be fooled: the test has plenty of functionality. I uploaded a six-minute audio video and it was transcribed in just a few minutes.
I recommend transcription as a finishing step in editing a video. Lock down your edit, then export a WAV audio tệp tin from your đoạn phim editor. If your ứng dụng doesn"t support exporting directly to lớn WAV, I recommend you use Audacity to lớn convert from other audio formats lớn WAV.
To upload audio, click on Select Audio File on the app page. Browse to lớn your WAV file and choose it. Watson also supports Spanish, French, Portuguese và Japanese, so make sure and choose the language from the dropdown if it differs from English. Note: If you use an ad blocking plugin for your web browser, make sure and disable it for the IBM website. The kiểm tra might not function correctly if adblock is enabled.
A few minutes later, you"ll have a transcription of the audio. At this stage, don"t worry about correcting all of the incorrect words in the transcription. Copy the text from the transcription box & save it into a text file, using an app like Notepad on Windows or TextEdit on mac.
If you are a capable programmer, IBM offers a much more in-depth way lớn use the Watson technology. Check out IBM"s tutorial on how lớn use the full Watson capabilities programmatically.

Paste in a links to your video, hit Begin, and Amara will load the đoạn phim into its subtitling system. Now it"s time to upload the transcription Watson generated for us. Click on Upload them directly on the left side of the screen to lớn upload the text tệp tin to Amara.
