Development of speech corpora in Gujarati and Marathi for phonetic transcription

There have been growing interest to use speech technology for rural areas. In this context, this paper describes the development of speech corpora in Indian languages (viz., Gujarati and Marathi from remote villages) for the task of phonetic transcription. This paper also presents related analysis of phonetic transcription. The manual phonetic transcription was done for two Indian languages, viz., Gujarati and Marathi for 8 hours of field recorded speech data in real-life settings. Dialectal variations are also analyzed using spectrograms and phonetic transcription. In addition, it was found that for consonant sounds, plosive sounds are having large coverage in broad phonetic category. The collected speech corpora can be very useful for speech and speaker recognition tasks.
