ASR-events-OC17

Introduction

The modern society demonstrates clear mutual influence among languages, e.g., Mandarin to minor languages in China, and English to other languages in the world. This leads to a clear mixlingual phenomenon, i.e., some words of a foreign (or target, embedded) language are embedded in a host (or source, matrix) language. This mixlingual phenomenon results in a serious problem in speech recognition (ASR).

Based on the success of the first MixASR-CHEN 2016 challenge, the MixASR-CHEN 2017 challenge follows the same theme of Mixlingual ASR. The task is more challenging in several ways:

• There are more utterances that involve multiple English words in the test data
• There are more English words that are not in the CMU dictionary
• There are more English phrases that involve multiple English words
