XVF3000

The XVF3000 voice processor provides far-field voice capture for smart speakers and conference calling applications.

The XVF3000 is now moving to end-of-life status with last time buy 31 March 2025.
This device has been replaced in the XMOS catalogue by the new XVF3800 which has improved performance, a smaller device package and greater value and the XCORE-VOICE platform that supports multiple keyword recognition engines. See EOL notice here.

OVERVIEW

The XVF3000 4-mic voice processor is designed for challenging acoustic environments. Acoustic echo cancellation (AEC) removes playback audio, enabling barge-in. Automated noise suppression and dereverberation remove unwanted noise and beamforming tracks and captures the voice of interest as it moves around a room.

You can parameterise and fine-tune the system to your product acoustics. With the choice of linear and circular mic-arrays, the XVF3000 is ideal for centre-of-room and edge-of-room conference-calling applications.

KEY FEATURES

Acoustic Echo Cancellation (AEC)

Acoustic Echo Cancellation removes echo from the microphone audio input and enables the XVF3000 to detect voice signals even when high-volume audio is playing through the product, enabling barge-in across the audio stream.

Adaptive Beamformer

The adaptive beamformer identifies the ‘Direction of Arrival’ and isolates the voice of interest. This can be read to the host processor or, in a conference calling application, converted into LEDs to indicate who is speaking.

Noise Supression

Noise Suppression nulls stationary and non-stationary diffuse noise sources, for example air-conditioning and road noise where the frequency characteristics don’t change over time. This enables accurate, consistent voice detection.

Automatic Gain Control (AGC)

The Automatic Gain Control tunes the output channels for best results, whether that’s for an Automatic Speech Recognition Service (ASR) or communications.

TESTIMONIALS

“We tested the XMOS voice processor against other solutions on the market, and it outperformed them all for clarity, accuracy, distance and direction. As we moved into development, the XMOS team were on hand whenever we needed them to help us resolve technical hurdles and secure the best possible performance outcomes. A great partner and collaborator.”
Emanuele Baglini, CTO

“Our sister brand AMR was one of the first premium Hi-Fi brands to adopt xcore® multicore microcontrollers back in 2011, and quickly realised that XMOS USB performance levels were far higher than other vendors. Since then we’ve used xcore® processors and their USB audio solutions across our range of award-winning, high-end audio products.”
Thorsten Loesch, Director of Technology
