Designing a Visual Front End in Audio-Visual Automatic Speech Recognition System
<p>Audio-visual automatic speech recognition (AVASR) is a speech recognition technique integrating audio and video signals as input. Traditional audio-only speech recognition system only uses acoustic information from an audio source. However the recognition performance degrades significantly in …

Implementing a distributed approach for speech resource and system development
The range of applications for high-quality automatic speech recognition (ASR) systems has grown dramatically with the advent of smart phones, in which speech recognition can greatly enhance the user experience. Currently, the languages with extensive ASR support on these devices are languages that …

Surface electromyography based speech recognition system and development toolkit
This thesis describes the implementation of an automatic speech recognition system based on surface electromyography signals. Data collection was done using a bipolar electrode configuration with a sampling rate of 5.77 kHz. Four feature sets, the short-time Fourier transform (STFT), the dual-tree …

Fractal based speech recognition and synthesis
… message is most often the primary purpose of speech communication and the recognition of this message by machine that would be most useful. This research consists of two major parts. The first part presents a novel and promising approach for estimating the degree of recognition of speech …

Semi-supervised cycle-consistency training for end-to-end ASR using unpaired speech
… introduces a new method to train end-to-end automatic speech recognition (ASR) models using unpaired speech. In general, large amounts of paired data (speech and text) are needed to train an end-to-end automatic speech recognition system. To alleviate the problem of limited paired data, the …

SegmentPerturb: effective black-box hidden voice attack on commercial ASR systems via selective deletion
Voice control systems continue becoming more pervasive as they are deployed in mobile phones, smart home devices, automobiles, etc. Commonly, voice control systems have high privileges on the device, such as making a call or placing an order. However, at the same time, they are vulnerable to voice …
