Flexible Voice Communications with TalkTogether™

Redefine what good voice communication sounds like with a scalable solution for voice communication that resolves acoustic echoes, speaker distortions, and background noises. Design your products for close-talk or far-field voice communication and build anything from control panels to soundbars to enterprise conference systems with expansion microphones, while receiving Amazon ACM (Alexa Calling, Messaging and Announcements) pre-certification. Combine with TalkTo™ to enable your product with a voice assistant and voice calling capability.

Ultimate Flexibility

Supports every imaginable use case from simple alarm panels to high-end conferencing systems. Flexible microphone arrays and playback options.

Robust Double Talk

Easily hear everyone on the call even when multiple people are talking. So good it even enables new applications like voice calling while gaming or watching tv.

Open I.P.

No more dealing with “black box” I.P. We open up the signal flow so you can extend & customize TalkTogether’s functionality with Audio Weaver and its 500+ modules.

OVERVIEW

TalkTogether brings natural, full-duplex, person-to-person voice communication to the Audio Weaver platform. Fully integrated with our graphical design platform, TalkTogether removes the complexity and risk when designing and deploying voice on personal, workplace, gaming, and public communications devices. Combined with TalkTo for human-to-machine communication, TalkTogether gives innovators a full suite of easily deployed solutions for clear voice, near or far, single or multiple voices, in quiet or noisy environments.

 

Reduce Friction While Improving Voice Quality

Adaptable Design: TalkTogether supports a wide spectrum of applications and can be customized to develop a voice calling system focused for any unique use-case. TalkTogether seamlessly integrates with TalkTo to activate voice calls using commands and meets the highest quality level within ACM (Alexa Calling, Messaging and Announcements). Teams and Zoom certifications are in progress and expected later this year. Current market segments include:

  • Huddle Room Conferencing
  • USB / BT voice pucks
  • Enterprise Boardroom Conferencing Systems
  • Smart Speakers
  • Gaming Soundbars
  • Smart Exercise Equipment
  • Medical Voice Communications
  • See everything TalkTogether can support
...

Robust Double Talk is when multiple people on the call speak at the same time and are still able to clearly understand each other. Speaker distortions, system delays or challenging ambient noises can all impact double talk performance. TalkTogether provides superior double talk performance with clear voice quality even for challenging situations like gaming, where loudspeaker output includes high volume game sound effects and introduces continuous double talk.

...

Acoustic Echo Cancellation (AEC) loudspeaker signals from the microphones allowing you to communicate without being tripped up by echoes. TalkTogether’s superior AEC supports mono, stereo, and even multi-channel playback applications. The highly optimized algorithm can handle long echo tails and track path changes.

...

Noise Suppression eliminates ambient noises such as keyboard clicks and the sound of crinkling wrappers while preserving speech quality. Together with Beamformers and Single Channel Noise Reduction (SCNR) that suppress stationary HVAC noises, TalkTogether’s Noise Suppression suppresses hard to remove non-stationary and transient noises such as keyboard clicks, game effects, etc. to deliver natural, noise-free communication in the Tx direction. This also includes optional blocks to enhance speech quality in specific environments:

  • De-Reverb removes the effects of reverberation in tightly enclosed spaces such as offices or living rooms with reflective walls. TalkTogether De-Reverb extends the echo canceller performance in huddle room conferencing and gaming scenarios to provide reliable speech quality.
  • Wind Noise Suppression delivers crystal-clear speech in extreme wind noise conditions extending voice communication capabilities to outdoor applications such as security cameras, video doorbells and hearables.
...

Direction of Arrival (DoA) determines the direction of the desired voice signal and can be used to steer video cameras at the person speaking. The DoA works in conjunction with the beamformer to focus in on the desired speech while rejecting reverberation.

  • Performance improves with increasing SNR
  • DoA information can be used in the product application to enhance usability
...

Tx and Rx Automatic Gain Control (AGC) allows rapidly changing speaker volumes to be dynamically adjusted to a consistent speech level thus normalizing loud and quiet talkers. TalkTogether Tx and Rx AGCs adapt to variations in speech levels, primarily in conferencing applications where the talkers can be loud or quiet, near or far from the device, using hangouts or Zoom for communications.

...

Loudspeaker Processing includes Equalizer (EQ), Dynamic Range Compression (DRC) together with an AGC to dynamically equalize the Rx signal spectrum and deliver clear, distortion-free speech in the Rx direction. TalkTogether Rx processing can be further extended with 500+ audio processing blocks available on Audio Weaver to enhance speech quality in receive direction.

...

Occupancy Detection turns the device On or Off automatically when the device recognizes an individual present in the room or vice versa. TalkTogether integrates occupancy detection using the existing speaker-microphone pair without the need for additional motion sensor components.
