THCHS-30

Speech data is crucially important for speech recognition research. There are quite some speech databases that can be purchased at prices that are reasonable for most research institutes. However, for young people who just start research activities or those who just gain initial interest in this direction, the cost for data is still an annoying barrier. We support the `free data' movement in speech recognition: research institutes (particularly supported by public funds) publish their data freely so that new researchers can obtain sufficient data to kick of their career.Here, we follow this trend and release a free Chinese speech database THCHS-30 that can be used to build a full- edged Chinese speech recognition system.

语音数据对于语音识别研究至关重要。当前已有多款语音数据库可供购买，其定价对多数科研机构而言较为亲民。然而，对于刚涉足该研究领域的新手，或是初次接触此方向的入门爱好者而言，数据采购成本仍是一道令人头疼的门槛。我们响应语音识别领域的“免费数据”倡议：由公共经费支持的科研机构应免费公开其采集的数据集，使新手研究者能够获取足够支撑其学术生涯起步的数据资源。本数据集正是顺应这一趋势，发布了一款免费中文语音数据库THCHS-30，可用于构建完备的中文语音识别系统。
