When that level of speech is achieved, scientists will have cleared the first of two enormous hurdles that are impeding the way toward humanlike interaction between computers and people.
Hence, it is expected that reduction in the speech distortion and increases in the SNR of the processed speech are achieved.
Using an efficient adaptive dual-band approximation of the LPC excitation, where voicing transition frequency is determined based on the concept of instantaneous frequency in the frequency domain, near natural sounding synthesized speech is achieved.
The effect of Kenny's speech is achieved by Stone mumbling into his own hand as he provides Kenny's lines, while the recorded audio is then edited with Pro Tools, and the pitch is altered to make the voice sound more like that of a fourth grader.
Further neurophysiological research is needed to constrain the possibilities on how auditory-visual integration in speech is achieved.
The rotation of speech is achieved by inverting the frequency spectrum around 2 kHz using a simple modulation technique; this retains spectral and temporal complexity, but makes the speech unintelligible (Blesser 1972).
An improvement of the perceptual evaluation of the speech quality (PESQ) value of 5% and more than 20% was achieved by the speech synthesis systems dealing with substitution disorders (SSD) and dysarthria, respectively.
Real-time audio feedback was achieved by instantaneous computer speech synthesis of predicted formant frequencies from the Kalman filter.
The speech reception threshold (SRT), at which 50% intelligibility was achieved, was calculated as the average of the last 10 answers.
In case of k-NN, the highest recognition was achieved for BFCC, 56.5% for acted speech and 74.5% for natural speech.
