Customer's Product to
Hit the Market in Q1 2025
Enhancing Consumer Headset Speech Quality to Professional
Grade
ZHUBEI, Dec. 30,
2024 /PRNewswire/ -- Airoha Technology announces the
launch of its flagship wireless audio chip, AB1595. This
groundbreaking chip integrates essential functions that currently
require multiple chips into one single system-on-chip (SoC) and
achieves Microsoft Teams Open Office certification level, setting a
new industry standard. The AB1595 significantly enhances speech
noise reduction through AI algorithm and the collaborative
processing of up to 10 microphones. It also improves the depth and
bandwidth of environmental noise cancellation, enabling real-time
filter adaptation to achieve consistent noise cancellation
experience across various users' wearing behaviors. The AB1595 has
been adopted by customers, with products expected to be available
in Q1 2025.
The AB1595 leverages Airoha Technology's extensive expertise in
wireless communication, AI audio, and hearing aid audio
technologies, overcoming numerous challenges to meet diverse
customer needs. AB1595 accelerates the development of AI audio
products that offer consumers a more comfortable, natural
conversation experience and higher quality.
First Flagship Wireless Audio SoC with Built-in AI Hardware
Accelerator
Airoha Technology's Senior Vice President, Yuchuan Yang, stated, "The AB1595 is not only
Airoha Technology's first flagship AI audio chip with a built-in AI
hardware accelerator but also the fifth-generation chip on the same
development platform provided to our customers. Airoha Technology
offers a comprehensive Software Development Kit (SDK) solution that
allows customers to reuse components developed in previous
generations and quickly integrate them with the AB1595, reducing
development costs and time to market. Additionally, Airoha
Technology's platform includes complete acoustic design
recommendations, including customized software, hardware
application notes, and tools to help customers accelerate the
development of differentiated end products."
Significant Enhancement in "Speech Noise Reduction"
Performance with Up to 10 Microphones
The flagship AB1595 chip from Airoha Technology brings the
stringent speech quality standards of professional-grade boom
microphones with Microsoft Teams Open Office certification to
consumer-grade boomless, omnidirectional headsets. By collaborating
with up to 10 microphones for ambient sound capture and using AI
algorithms to accurately identify and distinguish user voice and
environmental sounds, it achieves professional-grade speech
quality.
Compared to consumer-grade headsets, the AB1595 can enhance
"voice noise suppression" from 10 dB to as low as 40 dB, especially
in noisy environments like offices and cafes, significantly
optimizing speech quality and bringing professional-grade
teleconference functionality to consumer headsets.
Full Adaptive Active Noise Cancellation (ANC): The
AB1595 chips feature real-time adaptive ANC significantly enhancing
the depth and bandwidth of environmental noise attenuation. They
can further detect the user's wearing condition (i.e., good fit or
loose with leakage), performing adaptive compensation. The internal
filter settings automatically adjust based on the user's wearing
conditions and different environmental noise types, balancing the
best noise cancelling effect with the comfort of reduced ear
pressure, providing the most comfortable wearing, and listening
experience.
AI Conversation De-Noising: Even in noisy environments,
users can clearly hear the speech from the audience they are
speaking to while wearing the headset, such as on airplanes, in
stadiums, or on subways.
Achieving Low Power Consumption with 6-Core
Architecture
The AB1595 flagship chip is the industry's first 6-core
architecture design supporting Bluetooth transmission and AI audio
processing. By distributing computing tasks across multiple cores
and lowering operating voltage, it optimizes power consumption.
Given the high computational power required for intense AI audio
data processing and the need to extend usage time despite the trend
towards miniaturization that battery size need be reduced in
headsets, power-saving technology is crucial for overall energy
efficiency. Additionally, it could last 12 hours of the usage time
while hearing aid function is activated.
Airoha Technology adheres to the core development philosophy of
enabling users to "hear clearly, speak clearly, and move freely" in
the most natural way. We continuously explore technological
breakthroughs to provide users with a more natural and comfortable
experience. Senior Vice President Yang further noted, "The launch
of the AB1595 not only brings technological innovation to the
wireless audio industry but also, driven by user needs across
various scenarios, breaks down the deep technical barriers that
previously existed in consumer, gaming, enterprise, and hearing aid
fields. Airoha Technology, already a leader in these areas, will
lead the trend of integrated compatibility, allowing consumers to
enjoy professional-grade speech experiences in different
scenarios."
