Western countries entertain speech recognition-based applications. The experiment could be conducted in very large scale by introducing more Bangla utterances, types of window frames, etc. In many cases, recognition rate reduces if the number of samples increased. Phoneme recognition result is 100% accurate in Mel frequency cepstral coefficient analysis (MFCC) for all the three types of window frames taken for both male and female voices used. For linear predictor coefficient (LPC) analysis, Hanning window frame found better accuracy rate than Hamming and Blackman window frames. For power spectral analysis (FFT), phoneme recognition using Hanning and Hamming windows shows higher (95%) accuracy than the Blackman window frame. Hamming, Hanning and Blackman windows are applied for framing to find the best one for Bangla speech recognition.

Speech signals are divided into thousands of frames.

Power spectral analysis, linear predictor coefficient, Mel frequency cepstral coefficient analysis method and feed-forward neural network are considered for experiments. Still, there are numerous scopes for research on Bangla phoneme recognition. You saw how a letter is written and might be pronounced, but there is nothing better than hearing the sound of the letters in a video or audio.This research is about Bangla (Bengali) phoneme recognition to investigate the role of different window frames (during framing) for speech recognition accuracy. ষ Sound of ‘sh’ when the tongue touches the roots of the teeth ফ Sound of ‘f’ if pronounced with closed lips ধ sound produced by coupling soft ‘d’ and ‘h’= ‘dh’ ণ Nasal sound when the tongue touches a bit away from teeth ঞ Just like ‘gn’ of gnome with a slight up movement of tongue

ঝ This is produced using the naval sounds while the tongue touches the upper part of mouth cavity

The better you pronounce a letter in a word, the more understood you will be in speaking the Bengali language.īelow is a table showing the Bengali alphabet and how it is pronounced in English, and finally examples of how those letters would sound if you place them in a word. Without it, you will not be able to say words properly even if you know how to write those words. Learning the Bengali alphabet is very important because its structure is used in every day conversation.
