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.

disadvantages of collision theory. i have always thought of the disadvantages of collision theory. also the advantages too. i strongly believe that it has advantages and disadvantages.

  Automated train station
Posted by: jinuaravind - 08-16-2017, 08:43 PM - Forum: General Seminar Topics - No Replies

Automated train station

[attachment=209]

Introduction

My project is about a automated railway system.The basic idea is to use the Grove kit to determine the time,to play the corresponding sound when a train reaches the station, and to know when the train reaches the crossover.

The crossover(1):

The PIR motion sensor detects the train , sends this information to the arduino and the microcontroller activates the red light on the LED , starts the buzzer and lets the barrier down with the help of the servo motor

RF ID

This part is used to identify the trains . Because there are 2 trains there was a need to add something unique to each train. I used 2 rf tags on the train and in the station an RF ID . When the tag changes the sound recorder will know and play a different message in the station.

Demo code will be in rfid.txt

  Delay Analysis for Maximal Scheduling With Flow Control in Wireless Networks

Delay Analysis for Maximal Scheduling With Flow Control in Wireless Networks With Bursty Traffic

We consider the delay properties of one-hop networks with general interference constraints and multiple traffic streams with time-correlated arrivals. We first treat the case when arrivals are modulated by independent finite state Markov chains. We show that the well known maximal scheduling algorithm achieves average delay that grows at most logarithmically in the largest number of interferers at any link. Further, in the
important special case when each Markov process has at most two states (such as Bursty ON/OFF sources), we prove that average delay is independent of the number of nodes and links in the network, and hence is order-optimal. We provide tight delay bounds in terms of the individual auto-correlation parameters of the traffic sources. These are perhaps the first order-optimal delay results for controlled queuing networks that explicitly account for such statistical information. Our analysis treats cases both with and without flow control.
