Welcome to Speech Recognition team in CSLT, RIIT, Tsinghua University.

Research focus:

1. Speech recognition

We are interested in large vocubulary speech recognition, particularly on the modern topics such as noise robust ASR, deep belief network, covariance modeling etc.

2. Speech analysis

Our research focuses on speech signal analysis, such as sparse coding, non-negative matrix factorization, speech signal separation, noise cancelation etc.

3. Spoken document retrieval

We focus on key word spotting, spoken term detection, spoken document retrieval, FST-based indexing.
