Fluent.ai announced an embedded voice recognition solution for True Wireless Stereo (TWS) and other hearable products running on the Cadence Tensilica HiFi 5 DSP in partnership with Airoha, a MediaTek subsidiary. The solution is part of an integration available on DSP Concepts’ Audio Weaver platform, which provides OEMs a rapid way to design and prototype audio features and capabilities.

Multiple perspectives to inspire you in the new year. A Market Update on Bone Conduction Transducers, an article on the development of the Taction Transporter haptic transducer, and a valuable article by Hans W. Gierlich explaining an effective approach for testing structure-borne sound applied to in-ear developments. Andrew Bellavia writes about why the FDA’s OTC hearing aid rule could be quickly obsolete, Adam Levenson introduces the new Audio Foundry automotive audio development platform, and René Christensen makes its debut with audioXpress, writing about simulation techniques

DSP Concepts announced the availability of a new toolkit for True Wireless Stereo (TWS) earbuds powered by its Audio Weaver development platform. The toolkit features a reference design optimized to run on the Cadence Tensilica HiFi 5 DSP in partnership with Airoha, a MediaTek subsidiary and manufacturer of low-power TWS Systems on Chip (SoCs). The development kit also includes a reference design with a fully operational earbud prototype designed by Knowles.
