To meet the high-quality voice demands of third generation wireless systems, designers must move away from the narrowband coding techniques used today toward wideband coding schemes. In these wideband ...

The transmission of speech from one point to another over GSM mobile phone network is something that most of us take for granted. The complexity is usually perceived to be associated with the network ...

Speech codecs are audio codecs that look for sound and language patterns. In addition, since the human voice falls into more limited audio range than music, a speech codec is able to achieve the ...

Also called a "voice codec" or "vocoder," it is a hardware circuit that converts the spoken word into digital code and vice versa. It comprises the A/D and D/A conversion and compression technique ...

Broadband wired and wireless internet connections are getting faster all the time. But in many parts of the world high-speed internet access is unavailable and/or unreliable. So researchers continue ...

The codec performs speech encoding/decoding independently on a frame-by-frame basis. Other features include a 32-kb/s encoded bit stream rate, frame size of 16 ms, an algorithmic delay of 20 ms, and ...

In a bid to put an end to the all-too-familiar choppy, robotic voice calls that come with low bandwidth, Google is open-sourcing Lyra, a new audio codec that taps machine learning to produce ...
