Speech Recognition - HOTGUYS2121 - 08-16-2017 SPEECH RECOGNITION TOPICS What is speech recognition? Two main subsystems of speech recognition : - LPC(LINEAR PREDICTIVE CODING) -MFCC(MEL-FREQUENCY CEPSTRAL COEFFICIENTS) What are LPC and MFCC exactly? Calculation of these coefficients to improve reliability of speech recognition systems. Shortcomings that need to be improved. Applications Conclusion Introduction to Speech Recognition Technique Speech recognition is the process of converting an acoustic signal, captured by a microphone or a telephone, to a set of words. These words can serve as an input to further linguistic processing in order to achieve speech understanding A Speech Recognition system consists of the following components: Signal processing, speech decoding, and adaptation. A speaker generates a word sequence which is passed through a communication channel to produce a waveform. The speech waveform is passed to the signal-processing component of the speech recognizer which will generate a parameterized acoustic signal. The speech decoder component decodes the MEL FREQUENCY CEPSTRAL COEFFICIENTS In sound processing, the Mel-Frequency cepstrum is a representation of short-term power spectrum of sound, based on a linear cosine transform of a log power spectrum on a nonlinear mel scale of frequency. Mel-frequency cepstral coefficients (MFCCs) are coefficients that collectively make up an MFC. They are derived from a type of cepstral representation of the audio clip (a nonlinear "spectrum-of-a-spectrum" Basic working principle pf LPC The general algorithm for linear predictive coding involves an analysis or encoding part and a synthesis or decoding part. In the encoding, LPC takes the speech signal in blocks or frames of speech and determines the input signal and the coefficients of the filter that will be capable of reproducing the current block of speech. This information is quantized and transmitted. In the decoding, LPC rebuilds the filter based on the coefficients received. Speech Recognition - rjuntr - 08-16-2017 Language is man's most important means of communication and speech its primary medium. Speech provides an international forum for communication among researchers in the disciplines that contribute to our understanding of the production, perception, processing, learning and use. Spoken interaction both between human interlocutors and between humans and machines is inescapably embedded in the laws and conditions of Communication, which comprise the encoding and decoding of meaning as well as the mere transmission of messages over an acoustical channel. http://ziddudownload/5548905/speechrecognition.rar.html Speech Recognition - damani05 - 08-16-2017 please read http://seminarsprojects.net/Thread-speech-recognition-full-report http://seminarsprojects.net/Thread-Artificial-Inteligence-for-speech-recognition http://seminarsprojects.net/Thread-SPEECH-RECOGNITION-USING-DSP-full-report where documentation about speech recognition added Speech Recognition - [email protected] - 08-16-2017 you can refer these page details of "Speech recognition"link bellow http://seminarsprojects.net/Thread-speech-recognition-full-report http://seminarsprojects.net/Thread-speech-recognition-full-report?page=2 http://seminarsprojects.net/Thread-speech-recognition-full-report?page=3 Speech Recognition - abdul khader - 08-16-2017 Hi friend refer this page for more details on speech recognition http://seminarsprojects.net/Thread-speech-recognition-full-report http://seminarsprojects.net/Thread-speech-recognition-full-report?page=2 http://seminarsprojects.net/Thread-speech-recognition-full-report?page=3 Speech Recognition - eh.mahe - 08-16-2017 Hello, I am doing the project on speech recognition and i want algorithm to speech to text conversion and related information to this project.
