I'm looking for a way to integrate opus-codec (the decoder part) with my Android application.
Do you know of any implementations that have done so? We are currently using ogg-vorbis for spoken prompts, considering going with either speex (deprecated, but with few documented attempts) or opus (currently no documented attempts).
If we would have to go the NDK route, do you think it should provide us with a application size improvement? OggVorbis is supported by the platform, neither speex nor opus are.
