Fortemedia Announces a Low Power, Key Word Spotting Voice Trigger and Control IC

Santa Clara, CA (December 10, 2014) – iM401D is a mini digital signal processor for voice trigger and command processing.

Today Fortemedia announced the production availability of its iM401D low power, keyword spotting voice trigger and control IC. The iM401D is a mini-DSP (digital signal processor) designed for voice trigger and voice command processing. The iM401D is a purpose-built, all-digital product that supports digital microphone input. Not only is the iM401D built to support voice trigger and key phrase detection, but also one shot command recognition with third party algorithms.

The iM401D provides an extremely low power solution for always-on device voice control applications. It has a flexible digital voice detection system that provides exceptionally low power operation when listening for the onset of voice commands. With its low power operating modes, the iM401D also enables voice control to be provided on virtually any consumer electronics device.

The iM401D occupies a tremendously small footprint and is available in a WLCSP package with dimensions of 1.385L x 1.889W x 0.55H mm, or in a DFN package with dimensions of 3L x 3W x 0.85H mm. Thanks to its particularly small size, the iM401D can be incorporated into any consumer electronics product, ranging from tablets and smart phones to small wearable devices.

Presently, the iM401D is available with Sensory Inc’s TrulyHandsfree™ Voice Control product that supports the features of:

• A pre-defined key word trigger with optional speaker verification threshold (SVT)

• A user-defined key word trigger with SVT

• Pre-defined command phrase recognition

Multiple languages are supported and proprietary, and pre-defined key phrases can be developed in conjunction with Sensory, Inc.

Paul Huang, CEO and Chairman of Fortemedia stated, “We are excited to bring this low power voice input processing product to the market. We believe that the iM401D will enable voice control on a wide variety of new products and make wearable devices easier to use and operate.”

Sensory CEO Todd Mozer added, “Sensory is focused on working closely with industry-leading companies like Fortemedia to deliver the highest performance, ultra-low power, must-have speech solutions to our mutual customers. The iM401D and TrulyHandsfree Voice Control are an excellent example of the value these partnerships create.”

Fortemedia will be demonstrating the iM401D at the upcoming Consumer Electronics Show in Las Vegas, Nevada, January 6th-9th, 2015 in Suite 1665 of the LVH Hotel adjacent to the Las Vegas Convention Center. Please contact Jim Bohac at Fortemedia to arrange for a demonstration.
