1 Automatic speech recognition system architecture Circuit Diagram Overall scheme design 1.1 Principles of speech recognition. In computer systems, the uncertainty, dynamics, and continuity of speech signals themselves are difficult points for speech recognition. The mainstream speech recognition technology is based on the basic theory of statistical pattern recognition. 2.1 Controller circuit
Design and Applications of Embedded Systems for Speech Processing 177 2.2.2 Circuit design The use of improved partitioned look-up tables is another commonly used method to perform such elementary functions as logarith m, square root, and trigonometric functions, for example. Figure 2(a) shows the proposed four-s tage pipeline architecture. (a) In recent years, speech recognition technology has been applied to computer-aided language learning system [5]. e oral English learning mode of collecting the oral voice of the tester, evaluating Speech recognition is a technology field that captures, interprets, and computes a voice to transform it into text (TTS). Once the voice has been transformed into text, it can be applied to different applications, from speech dictation, to command-voice controllers, health monitoring, robotics and artificial intelligence or accessibility, among

This article details the construction and building of a stand alone trainable speech recognition circuit that may be interfaced to control just about anything electrical, such as; appliances, robots, test instruments, VCR's TV's, etc. The circuit is trained (programmed) to recognized words you want it to recognize. Link. In this paper, we present a low cost circuit design for a sentence speech recognition. The basic circuit of the designed sentence speech recognizer is composed of resistor, capacitance, OP Amp, counter and logic gates. Through a sentence recognition experiment, we can find the effectiveness of the designed sentence recognition circuit At its most basic level speech recognition allows the user to perform parallel tasks, (i.e. hands and eyes are busy elsewhere) while continuing to work with the computer or appliance. This circuit allows one to experiment with many facets of speech recognition technology. The heart of the circuit is the HM2007 speech recognition integrated circuit.

The Since it does not rely on a server with an internet connection for the voice recognition, the recognition is fast and privacy concerns are not an issue. On the other hand, the voice recognition is speaker dependent and the recognition is limited to simple phrases. Also, I found the recognition accuracy of very low, definitely below the 99% stated.
