Title human and automatic speaker recognition over telecommunication channels: authors(s. 1 study of speaker recognition systems a thesis submitted in partial fulfilment of the requirements for bachelor in technology in electronics & communication. • to develop and test a speaker independent speech recognition system via two approaches, the first one being the template matching approach using the vq and lpc algorithms while the second approach is the zero crossing technique.
Asr for el speech 2 automatic speech recognition asr systems convert speech into text the basic idea is to extract a set of features from a speech signal and to use those along with the transcription to create a statistical model. Speaker recognition system makes it possible to use the speaker's voice to verify his/her identity and control access to services such as voice dialing,telephone banking,telephone shopping,voice mail and other computer. Referring to the figure 1 below, we can see that a speaker recognition system is composed of the following modules: front-end processing - the signal processing part, which converts the sampled speech signal into set of feature vectors , which characterize the properties of speech that can separate different speakers. System learns directly from data, we do not require specialized components for speaker adaptation or noise ﬁltering in fact, in settings where robustness to speaker variation and noise are critical. Iii abstract the work leading to this thesis has been focused on establishing a text-independent closed-set speaker recognition system contrary to other recognition systems, this.
Speaker recognition is the identification of a person from characteristics of voices (voice biometrics) it is also called voice recognition there is a difference between speaker recognition (recognizing who is speaking) and speech recognition (recognizing what is being said. Potentially large group of voices unknown to the system in today's technological world verification is the basis for most speaker recognition applications and the most commercially feasible task [5.

In this paper, we describe sphinx, the world's first accurate large-vocabulary speaker-independent continuous speech recognition systemwe will present current results of sphinx, compare its performance against similar systems, and account for its high accuracy. Evaluation of speech and speaker recognition systems has proved to be invaluable in comparing diﬀerent approaches, sharing results, and generally advancing the technology state-of-the-art in this chapter we. The dissertation speaker recognition by todor dimitrov ganchev has been examined and approved by the following examination committee. This thesis deals with a text based speaker identification system ie, to find the identity of a person using his/her speech from a group of persons already enrolled during the training phase feature extractor is the first component in a speaker recognition system.
In this thesis we focus on speaker recognition systems that run entirely on mobile or other resource limited device that does not require additional infrastructure to operate. In this thesis, we describe a variety of approaches that make use of multiple streams of information in the acoustic signal to build a system that recognizes the regional dialect and accent of a speaker. Figure1 (a) speech recognition system without speaker identification figure1 (b) speaker identification followed by speech recognition this paper focuses on the implementation of speaker identification and enhancement of speech.
