A final section presents MATLAB programs for a speech coder
and a music coder.
RealSpeak Word uses a new approach to achieve high quality synthesis for predefined words and idioms based on a coding-by-synthesis model rather than the traditional method of recording the audio data and then using a speech coder
The speech coder
is based on a residually excited linear predictive coder, enhanced by including a long term predictor (LTP).
He was also a senior research engineer in AT&T Bell Labs where he developed voice and video compression technologies, including the speech coder
that is now the standard for CDMA cellular in North America.
Its DSP cores are architected to maximize the density of SMV (IS-893), the latest speech coder
used in CDMA2000 networks.
This patent-pending technique is based on a coding-by-synthesis model rather than the traditional method of recording the audio data and then using a speech coder
ARM Codec is a speech coder
for compression/decompression, is a piece of software that compresses digitized speech to reduce transmission channel or storage capacity requirements, and then decompresses received samples to reconstruct the original speech signal with minor loss in signal quality.
2 Adaptive Multi-Rate Wideband (AMR-WB) speech coder
AMR is a low bandwidth speech coder
standard, designed especially for use in next generation 2.
We are employing proprietary packet-voice-specific instructions to achieve lightning-fast speech coder
algorithm execution," explained H.
Ericsson will also provide GMCC with its Enhanced Full Rate speech coder
solution, which improves the voice quality of GSM, particularly for women and children's voices, which have higher frequencies than men's.
1, an international standard established by the International Telecommunications Union and the speech coder
recently selected by the Voice over IP (VoIP) Activity Group, part of the International Multimedia Teleconferencing Consortium (IMTC), as the preferred speech coder
for Internet telephony over modem connections.
