Speech processing algorithms for VoIP and VoP gateways
Product description:
DIGITAL SPEECH offers the base speech algorithms for VoIP and VoP gateways: optimized standard vocoders, line echo cancellers, adaptive jitter buffer, PLC, Time Scale Modification algorithm. CPTD, DTMF detectors and generators will be available soon.  DIGITAL SPEECH offers optimized ANSI C algorithms which can be ported to any platform. For same platforms optimization already was done.
