MindTree offers a selection of speech codecs and algorithms designed to suit the needs of various applications, bit rate requirements, and voice qualities. Our range of speech codecs is thoroughly tested for conformity to specifications from different standards bodies, such as 3GPP, 3GPP2 and ITU-T. MindTree Speech Codecs are thoroughly tested for respective standard compatibility and are highly optimized for MIPS and memory requirements.

MindTree has significant exposure to algorithm implementations for speech applications such as Echo Cancellation and Noise Reduction (ECNR), Voice Activity Detection (VAD), and Speech Recognition. In addition, we offer Customization of Speech codecs to your requirement, integration of speech codecs into end user applications, as well as Porting and Optimizing them onto your specific processor platforms.
