Tree Structured Vector Quantization Based Technique For Speech We introduce vector quantization in the field of contex tual speech recognition as a viable technique to discre tize biasing embeddings and approximate the compute heavy cross attention mechanism, achieving over 20% speed boost and 85 95% memory usage reduction. In this paper, a vector quantization model that incorporate rough sets attribute reduction and rules generation with a modified version of the k means clustering algorithm was developed.
Pdf Vector Quantization Vector quantization and dynamic time warping (dtw) are examples of template models for text independent and text dependent recognition, respectively. in stochastic models, each speaker is modeled as a probabilistic source with an unknown but fixed probability density function. We propose using vector quantization instead of scalar quantization in a speech coding framework. the experiments show that the decoded speech has a higher perceptual quality because vq considers the correlation between different dimensions of spectral envelopes. This work proposes an approximation to cross attention scoring based on vector quantization and enables compute and memory efficient use of large biasing catalogues. we propose to use this technique jointly with a retrieval based contextual biasing approach.

Vector quantization (vq) is a lossy data compression method based on the principle of block coding. vector quantization can be thought of as a process of redundancy removal that makes the effective use of nonlinear dependency and dimensionality by compression of speech spectral parameters. Abstract in the vector quantization, the main task is to generate a good codebook. the distortion me. sure between the original pattern and the reconstructed pattern should be minimum. in this paper, a prop. sed algorithm called modified k meanslbg algorithm used to obtain . ey. ords: k mean. Vector quantization reduces distortion by efficiently mapping vast feature vectors into predefined clusters, thus improving recognition by consolidating speaker specific features. Ning vector quantization (lvq) neural network and particle swarm optimization (pso) technique. this method is applied into two phases, in the first phase mfcc and lpc feature extraction technique, learning vector quantiza.
