DIOTEK to Integrate Speech Recognition Engine with Conexant CX20805 DSP

DIOTEK will integrate their speech recognition technology with Conexant’s CX20805 digital audio processor. DIOTEK’s speech recognition engine complements Conexant’s digital audio processor, which features a comprehensive collection of pre- and post-processing algorithms and far-field voice input technology. The integrated solution is ideal for smart home appliances, consumer electronics and educational toys.

Enabling voice commands for many products is challenging. For home appliances, ambient noise and distance must be taken into consideration. Conexant has addressed these issues with its pre-processing algorithms that include noise reduction and far-field voice input processing. Conexant provides the hardware and advanced pre-processing algorithms to filter out ambient noise and provide a good hit-rate for DIOTEK’s speech recognition engine to produce reliable voice control from far away.

Target areas of automatic speech recognition (ASR) segmentation include:

  • Voice Wake Speech Recognition
    Power-on scenario with no audio playback and magic word scenario with audio playback
  • Keyword Recognition
    Full ASR on-chip parameter feature extraction, lookup, recognition, and fixed words library
  • Natural Language
    Cloud-based recognition and response

The CX20805 from Conexant is a dual-core 32-bit, high-performance, low-power digital audio processor for applications with demanding audio requirements. Based on the Conexant Audio Processing Engine (CAPE) architecture with scalable performance of up to 800 MIPS, the CX20805 integrates high-speed USB 2.0 and other key audio interfaces with advanced power management functionality.
