Speech Signal Compression Algorithm Based on the JPEG Technique

open access: yesJournal of Intelligent Systems, 2018
The main objective of this paper is to explore parameters usually adopted by the JPEG method and use them in speech signal compression. Speech compression is the technique of encoding the speech signal in some way that allows the same speech parameters ...

DeepVoCoder: A CNN model for compression and coding of narrow band speech [PDF]

open access: yes, 2019
This paper proposes a convolutional neural network (CNN)-based encoder model to compress and code speech signal directly from raw input speech. Although the model can synthesize wideband speech by implicit bandwidth extension, narrowband is preferred for

Signal-to-Noise-Ratio-Aware Dynamic Range Compression in Hearing Aids

open access: yesTrends in Hearing, 2018
Fast-acting dynamic range compression is a level-dependent amplification scheme which aims to restore audibility for hearing-impaired listeners. However, when being applied to noisy speech at positive signal-to-noise ratios (SNRs), the gain function ...

Effect of the number of amplitude-compression channels and compression speed on speech recognition by listeners with mild to moderate sensorineural hearing loss.

open access: yesJournal of the Acoustical Society of America, 2020
The use of a large number of amplitude-compression channels in hearing aids has potential advantages, such as the ability to compensate for variations in loudness recruitment across frequency and provide appropriate frequency-response shaping.

Traditional Psychoacoustic Model and Daubechies Wavelets for Enhanced Speech Coder Performance

open access: yesInternational Journal of Technology, 2015
Speech compression techniques based on traditional psychoacoustic model have been proposed by many researchers. We have suggested Discrete Wavelet Transform (DWT) supported by the same psychoacoustic model for speech compression.

Interactive Multimedia Association-Adaptive Differential Pulse Code Modulation Codec With Gated Recurrent Unit Predictor

open access: yesIEEE Access
Speech coding is important for effective storage and transmission of audio signals. However, current Interactive Multimedia Association Adaptive Differential Pulse Code Modulation (IMA-ADPCM) speech coding techniques that use a fixed predictor have an ...

A Comparison of Front-Ends for Bitstream-Based ASR over IP [PDF]

open access: yes, 2006
Automatic speech recognition (ASR) is called to play a relevant role in the provision of spoken interfaces for IP-based applications. However, as a consequence of the transit of the speech signal over these particular networks, ASR systems need to face ...

Sequence-level Knowledge Distillation for Model Compression of Attention-based Sequence-to-sequence Speech Recognition [PDF]

open access: yesIEEE International Conference on Acoustics, Speech, and Signal Processing, 2018
We investigate the feasibility of sequence-level knowledge distillation of Sequence-to-Sequence (Seq2Seq) models for Large Vocabulary Continuous Speech Recognition (LVCSR).
