The development kits and reference designs will be powered by Conexant’s CX20924 4-microphone and CX20921 2-microphone voice input processing solutions. DuerOS is a conversation-based AI system that already supports access to a voice-activated digital assistant for mobile phones, TVs, speakers, and other devices.
Enabling speech recognition and voice control from a distance requires overcoming substantial acoustic challenges related to echo cancellation, background noise, position of microphones, speaker placement and more. The 2-mic and 4-mic development kits for DuerOS will help shorten time-to-market of conversation-based AI devices with high-performance noise cancellation and far-field voice capability.
“Voice interface is a critical part of DuerOS and we are committed to working closely with Conexant to quickly grow the DuerOS ecosystem by offering product developers a solution to help them quickly fulfill consumer demand for top-performing AI-infused devices,” says Baidu’s Kun Jing, “we’re working closely with Conexant to ensure their voice solutions provide optimal speech recognition performance with our AI system and are excited to provide device makers tools to jumpstart the creation of new hardware applications.”
The core component in the announced development kits is Conexant’s AudioSmart voice input processor (CX20924 for 4-mic applications, and CX20921 for 2-mic applications) running its industry-leading far-field voice pre-processing software technology. Conexant’s far-field voice input processors focus on the user’s voice and remove echoes and noise from the audio signal to provide the DuerOS cloud AI platform clear voice requests for speech recognition processing. Conexant’s market-proven voice processing provides a consistently accurate AI experience.
Benefits of the Conexant AudioSmart voice input processors include:
· Robust far-field voice interaction with two or four microphones
· Proprietary Smart Source Locator technology identifies the direction from which the user’s voice is coming (4-mic only)
· Enhanced Smart Source Pickup noise suppression improves speech recognition performance by filtering non-stationary TV noise and voices coming from sources other than the user out of the audio signal
· Voice barge-in enabled by full duplex acoustic echo cancellation (AEC) detects the wake word even when the device is playing music or voice prompts loudly
The collaboration is aimed at helping developers and device-makers integrate DuerOS into their own products. Conexant is the de facto far-field solution for voice-enabled products today, and through this partnership, Baidu and Conexant are establishing a high-performance standard for AI devices to come.
