PureAudio™ Speech Development Kit for Raspberry Pi

Raspberry Pi Microphone & Voice Recognition

PureAudio™ Development Kit: The Ultimate Raspberry Pi Microphone

When it comes to your IoT devices, Andrea’s got the powerful “ears” that can hear you, even in extremely noisy environments. That’s why we are used in millions of computers, police cruisers, robots, virtual teller machines (VTMs), customer service kiosks, intercom systems, and fast food restaurant drive thru order posts.

Our patented digital beam forming and adaptive noise cancellation signal processing enables accurate far-field speech recognition from up to 14 feet away, for a superlative performance in voice-operated IoT applications that require advanced audio input technology, including speech recognition microphones and noise reduction software.

What Is Raspberry Pi?

Raspberry Pi is a credit-card sized computing device that plugs into a computer monitor or TV, and uses a standard keyboard and mouse. The Raspberry Pi boasts a broad range of common computer abilities and applications, from internet browsing, to making spreadsheets, to word-processing, and gaming.

The Raspberry Pi has the ability to interact with the outside world, and has been used in a wide array of digital maker projects, making it a favorite among new and seasoned developers alike.

Raspberry Pi Microphone & Voice Recognition

For developers looking to enable the Raspberry Pi for voice recognition, a high-performance microphone and advanced noise-canceling software are vital for optimal performance and successful trigger-phrase detection.

A common problem with trigger-phrase detection is being able to detect the trigger-phrase when music is playing out of the speaker, located near the microphone. This is known as barging-in to the music in order to speak commands to the device.

The data below documents how Andrea’s audio filters significantly improve the barge-in performance of any speech recognition device, making the PureAudio™ Development Kit the ideal Raspberry Pi microphone.

The following graphs show the percent of successful commands from 2 feet (0.6 meters), 6 feet (1.8 meters), 10 feet (3.0 meters), 14 feet (4.3 meters) and 18 feet (5.5 meters).
