HI database-Tamil digits
Description
This database contains the speech samples from 10 deaf children aged 5-10 years studying at Maharishi Vidhya Mandir Service Centre for Hearing Impaired (HI), Tiruchirappalli. The deaf children are able to follow only one language, mostly their native language because they cannot follow the different facial expressions and throat vibrations. Like a Speech therapist, we have used the integration of tactile to record the speeches of hearing impaired. i.e. we make them to touch our throat by their hands to feel the vibration when pronouncing a particular word and ask them to see our facial expressions and listen to the sound. They have to visually see the words also, by writing them on the board. Among the ten children seven are profoundly deaf and three are hard of hearing. Children have spoken the Tamil digits 20 times and their corresponding speeches are recorded using high quality microphone. 15 speeches of 10 speakers are considered for training and remaining 5 speeches of 10 speakers are considered for testing. Initially the words are recorded using wave surfer and labels are given accordingly by manually hearing the sound. Care must be taken when assigning the labels since deaf pronunciation is poor; first, the word he or she has spoken is to be understood and labelled. Also, the pauses are not produced between the words by them; so silence must be introduced. Each speech sample is stored in PCM wave mono format with 16 kHz as sampling rate and16 bits for each speech sample. This database can be used for HI speech/speaker recognition.
