The OGI multi-language telephone speech corpus

The OGI Multi-language Telephone Speech Corpus is designed to support research on automatic language identi cation and multi-language speech recognition. The corpus consists of up to nine separate responses from each caller, ranging from single words to short topic-speci c descriptions to 60 seconds of unconstrained spontaneous speech. The utterances were spoken over commercial telephone lines by speakers of English, Farsi (Persian), French, German, Japanese, Korean, Mandarin Chinese, Spanish, Tamil, and Vietnamese. We have completed the initial phase of our data acquisition e ort: the recording and initial veri cation of utterances produced by 100 di erent speakers in each of the 10 languages. We describe the recording protocol, data collection procedure, ongoing corpus development, preliminary results of the statistical evaluation of the 10 languages, and plans to provide orthographic transcriptions of the speech.
