Industry-leading audio processing IP developed by DSP Concepts
TalkTo
An audio front-end (AFE) that delivers exceptionally clean audio signals to voice assistants and ASR engines
Easily integrate voice UI with support for Alexa Voice Service, Google Voice Assistant, and custom on-device voice solutions. TalkTo can scale from low-power, single-microphone solutions with quiescent sound detection and single-channel noise reduction, to advanced multi-microphone arrays with a host of advanced signal processing algorithms.
Highlights
- Extended pick-up range – reliable voice pickup even at 5 meters away
- Multichannel AEC – enables simultaneous voice conferencing with multichannel playback with up to 35 dB of cancellation


TalkTo Essential
Reliable far-field pickup for mono and stereo applications
TalkTo Advanced
Superior noise performance with stereo or multichannel playback and Direction Of Arrival
TalkTogether
Delivers natural, full-duplex, person-to-person voice communication
Seamlessly integrate full-duplex voice communication and meet the rigorous benchmarks required for Microsoft Teams certification. TalkTogether is ready to be tailored for a wide range of form factors from near-field half-duplex with basic ECNR to far-field multi-microphone systems with exceedingly robust echo cancellation and machine learning-driven noise reduction.
Highlights
- Robust double talk – scalable up to full-duplex with Residual Echo Suppression that meets Microsoft Teams requirements
- Configurable beamforming – combines Direction of Arrival functionality with adaptive capability to substantially increase signal-to-noise ratio
