The IBM Speech to Text API automatically transcribes English speech to text. Developers can use this API to add speech transcription capabilities to their applications. Speech recognition accuracy is highly dependent on the quality of input audio, and the service can only transcribe words that it knows. Thus, the conversion of speech to text may not be perfect. IBM Speech to Text is part of the Watson Developer Cloud and is currently still in beta.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
In this, developer-blogger Alex Kras shows us how to overcome the 60 second audio file limitation of the free tier of Google's Cloud Speech API by taking a longer audio file, breaking it up into short chunks, and then cycling through those chunks to make a complete transcription.
