Speech Enhancement and Coding

  • PowerPC/Altivec-based G.726 ADPCM codec
  • TMS320C6000-based G.729 speech codec
  • MATLAB-based model-based speech enhancement techniques
  • MATLAB-based generic speech models from training data using vector
    quantization and a Hidden Markov Model (HMM) approach
  • ADSP-21060-based HMM Speech Enhancement
  • MATLAB-based speech enhancement and speaker identification algorithms using the HMM approach
  • MATLAB-based Spectral Lateral Inhibition algorithm for speech enhancement in low SNR environments. Increased output SNR by 6 dB over original system
