Section 4 is dedicated to discussion on our proposed method for speech recognition enhancement in autocorrelation domain.
My musings on the topic have run to "recognition enhancement vaccines," essentially a form of immunization we could use to help the immune system distinguish more faithfully between native and foreign.
This object recognition search enhancement is based on the work done by two acquisitions Yahoo made last year: IQ Engines and Lookflow.
Typical applications of microphone array system include teleconferencing, automatic speech recognition, speech enhancement, source separation and automatic auditory system for robots [1 6].
For audio signals, frequency estimation plays a crucial role in parametric audio processing, which has been reported in various applications such as synthesis [9, 10], recognition [11], enhancement [12], and frame-loss concealment [13, 14].
We adopted the mel-scale to prevent being biased to any specific cases; this scale has been proven to be efficient in numerous speech signal-processing applications such as speech recognition and enhancement.
Voice activity detection (VAD) refers to the problem of distinguishing active speech from non-speech regions in an given audio stream, and it has become an indispensable component for many applications of speech processing and modern speech communication systems [1 3] such as robust speech recognition, speech enhancement, and coding systems.
The finding of recognition memory enhancement in the positive mood/high arousal condition might be predicted from studies showing that positive affect is associated with improved cognitive abilities including creative problem solving [10], spatial processing [11], [12] associative memory [9] and broadening of attention in health and disease [9], [13].
To further improve the recognition accuracy, the enhancements of three different kinds of distortions have been tested.
Following this idea, we propose a different VAD method which integrate our proposed VAD method (mentioned in Section 2) with the MMSE speech enhancement method, as shown in Figure 4. Figure 4 VAD based on the recursive of phoneme recognition and speech enhancement.
