11. Phoneticians were able to replay the speech signal several times and apply acoustic filters to the signal. 12. It is difficult to delimit a stretch of speech signal as belonging to a single perceptual unit. 13. By doing so, they were able to more carefully deduce the acoustic nature of the speech signal . 14. Schouten became manager of the telephony group, where he sought efficient methods to convey the speech signal . 15. Pre-emphasis is commonly used in telecommunications, digital audio recording, transmissions, and in displaying the spectrograms of speech signals . 16. This allows dropping of the least significant bit from the bit stream without adverse effects on speech signal . 17. The presence of multiple speech signals makes it difficult for the processor to correctly select the desired speech signal. 18. In this iterative fashion, listeners thus reconstruct the articulatory events which were necessary to produce the perceived speech signal . 19. Compared to known speech coders, the codec is capable of coding both music and speech signals with good quality. 20. The software, which detects and analyzes voice and speech signals , offers a technological alternative to an often intuitive process.
