Speechutils

Speechutils is an Android library that helps to implement apps that need to include speech-to-text and text-to-speech functionality. For example, it provides methods for

• audio recording and encoding
• aggregating speech-to-text and text-to-speech services
• playing audio cues before/after speech-to-text
• pausing the background audio during speech-to-text
