DIGITAL SPEECH offers the base speech processing algorithms for telephony applications: acoustic echo canceller, noise suppressor, automatic gain control, voice activity detector,  line echo cancellers, anti-howling system . CPTD, DTMF detectors and generators, caller ID will be available soon. Offered solution can be used in Hands-Free and Handset modes. DIGITAL SPEECH offers optimized ANSI C algorithms which can be ported to any platform. For some platforms optimization already was done.
