Introduction

This documentation serves as an introduction to the Yobe SDK. The library requires two channels of interleaved input audio data (either 16 bit PCM or double encoded) at a sampling rate of 16kHz. The library returns one channel audio data as output with a sampling rate of 16 kHz and some additional data in some cases.

NOTE: This SDK is updated. You should continue to apply the 8K down-sampler to the output, but you do not need to apply extra gain anymore.

SDK Variants

The Yobe Android SDK offers one variant:

• Near-CAFE Listening - Use cases when the voice of interest is closer to the microphone inputs than the background noise
• Far-CAFE Listening - Use cases when the voice of interest is farther from the microphone inputs than the background noise

Further Information

• There are functions in com.yobe.speech.SpeechUtil to assist integrating the Yobe library into your project.
• If you run into any problems, take a look at the logging capabilities in com.yobe.speech.SpeechUtil to get more information.
