NOR flash maker Spansion launched the 'Acoustic
Coprocessor', a human machine interface (HMI)
coprocessor that enables voice-controlled system
interfaces.
Leveraging Nuance Communications voice technology, the
new product is aimed at voice recognition systems in
automotive, gaming and consumer electronics, improving
response time and accuracy over conventional voice
interfaces by supporting larger acoustic databases.
Spansion Acoustic Coprocessor comprises custom-designed
logic and high-speed memory to accelerate and optimize
voice-enabled human machine interfaces, while offloading
the acoustic processing workload from a conventional
CPU.
Spansion Acoustic Coprocessor integrates custom-designed
logic and hardware with Nuance's VoCon software engine,
and provides a dedicated resource for natural user
interfaces such as voice.
Spansion's benchmark results demonstrate that with the
Spansion Acoustic Coprocessor, system response improves
by 50 percent over typical systems using an application
processor alone. The load on the application processor
lowers by up to 50 percent, freeing it for other tasks.
In addition, the Spansion Acoustic Coprocessor is able
to support larger databases with multi-lingual, gender
and tonal sounds, which in turn improves accuracy and
advances natural language understanding.
Spansion's first implementation is in the automotive
market where voice is providing a safer, smarter way to
stay connected behind the wheel, minimizing
visual-manual distractions posed by handheld devices.
The Spansion demo platform, which integrates Spansion's
technology and Nuance voice recognition software, is
currently being evaluated by automotive manufacturers,
with design samples available in the third quarter of
this year.
The company will initially offer two versions of the
chip, one supporting acoustic models for up to a dozen
languages and the other supporting three languages.
The chips link to applications processors over an SPI
bus. They include an internal 1.2 Gbytes/second data bus
to support fast memory searches.
The chips consume from 100 milliwatts to 1.5W, depending
on their size and fit in a 10mm2 QFN package. |
