Cupcake: Speech technology on Android

Tuesday, 27th January, 2009

In mid-December 2008 Google announced cupcake, an update to the Android platform. Here are some brief comments:

  • One of the new features listed under Framework is “Simplified SREC speech recognition API available”.
  • In the project layout srec is listed as an external project.
  • It’s in the source here.
  • The source is copyright Nuance and released under the Apache license. Here is an example copyright header (from AcousticModels.c):

  • As far as I can tell, there’s no discussion of srec on android-beginners or android-developers. According to Dave Sparks on android-developers (Jan 20), “We haven’t released a Cupcake SDK yet. Docs will come when the SDK is published.” I’ll keep you posted.
  • n.b.: Text-to-speech is available on Andriod, using the eyes-free TTS library.
