Question

As you probably know, implementing speech-to-text is pretty easy with the Android API. All you have to do is just call up the API’s intent and it will return text for you. My case is a bit different, I have a prerecorded 3GPP sound file that I’ve recorded from the user and is saved on the SD card. I want to know if it’s possible to transcribe that into text like any other speech recognition. Does the speech-to-text API allow for uploading you’re own sound files to be processed? Or is this impossible?

Answer 1

The API does not allow it, but see this blog post and its comments for a potential workaround. Also make sure that your file contains high quality audio (at least 16 bit and 16 kHz) to get a better transcription.
