DSP Group’s Ultra-Low-Power Development Kit Boosts Far-Field Speech Accuracy for Amazon Alexa Voice Service
HDClear 3-Microphone Development Kit Enables Superior Performance for AVS in Smart Speakers, Tablets, and Smart Home Products
With voice assistant devices in the US predicted to grow from 450 million units in 2017 to 870 million devices in 2022, according to
The announcement is of strategic significance as well.
“The migration toward voice user interfaces marks a sea-change in users’ interactions with electronic devices,” said
“We envision a future where customers interact with Alexa everywhere and from any device,” said
About DMBD5
DBMD5 is a completely autonomous, audio-centric processing solution that enables any microphone-equipped device to continuously monitor for voice trigger and process voice commands. It also supports advanced voice features that allow the device to facilitate voice calls. When integrated in smart speakers and IoT devices, DBMD5 leverages its voice enhancement algorithms to achieve more effective isolation of voice from surrounding noise, supporting effective voice gestures in almost any environment.
Key benefits of the HDClear 3-Mic Development Kit for Amazon AVS include:
- High-Performance Voice Enhancement Capabilities – sophisticated voice algorithms including acoustic echo cancellation, noise reduction, beamforming and far-field enhancement, significantly improving the user experience and the accuracy of voice commands, particularly in high-noise environments. Without these algorithms, devices with closely coupled speakers and microphones would be inadequate for voice functions.
- Barge-In – enables detection of voice commands when audio, including music, is played by the device.
- Seamless Operation with Amazon AVS – supports Amazon Alexa wake word and fully integrates with AVS SDK to ensure seamless operation with AVS.
- Advanced Audio SoC – embedded programmable dual-core DSP supports digital and analog microphones and incorporates various application processor interfaces such as SPI, I2C, UART and SLIMbus.
- Low-Power Consumption – power-optimized implementation for always-on IoT devices allows power-hungry application processors to remain in sleep mode during voice sensing, and also enables battery-powered devices to access Alexa. Power consumption well below 1mA for Alexa wake-word detection is supported.
- Far-Field Enhancement – high performance using 3 mics, allowing flexibility for up to 360-degree voice coverage.
- Local Detection of Alexa – enables low-power detection and integration in IoT devices with small amounts of memory for wake-word detection.
- Fast Time to Market – complete suite of host processor/communications processor/MCU software drivers enables rapid development.
- Scalable – software configuration supports various types of smart speakers, digital assistants, wearable computing devices, smart home devices, remote controls, IoT devices and more, accommodating different requirements for microphones, speakers, audio flow toward the speaker(s), audio flow from the microphones, and acoustic designs.
