Natural Human-to –Machine hands free Communication: Voice UI

AMI Technologies Voice User Interface (Voice UI) technology accelerating the development of the Far Field Mic array solutions to improve automatic speech recognition (ASR) for natural Human-to-Machine hands free communications. Our best 2 Mic or 4 Mic Far filed array provided the flexibility of adopting the technology to any voice enabled devices.

With the voice barge-in capabilities user can control the device from 5 meters to 8 meters distance even in noisy environments and playing the sound. Offline Trigger phrase or wake word integrated in our far filed technology will activate the device to send the clean audio data to the cloud services like Google or Amazon etc .

AMI Technologies and Amazon Alexa :

AMI Technologies offers the amazon web services integration along with our Voice UI technologies , this helps the OEMS and ODMs to go to the market fast and reduce the development time and cost . AMI Technologies noise reduction and echo cancellation software modules ensure the best performance and improve the ASR for hands free natural communication.

Technology

Our Far Field Mic Array reference design for Voice Enabled Devices like Smart Phones, Wearables, Hearables and IoT devices will offer very flexible design and tuning on the final product, it reduces the 90% development cost and time. It includes the below Speech Processing Modules along with the real time firmware to improve Trigger Word detection and Automatic Speech Recognition (ASR)

Speech and Noise Reduction Algorithms

  4. Real Time Framework to render the Speech and Audio
  5. In house development team to support the integration of custom Triggers for example Alexa skills etc

Tuning Tool

  1. Flexibility to real time tuning and further tweaking the signal flow is important while building the product, OEMs and ODMs also want to differentiate their product with competitors by scale the system with new features. AMI Technologies provides its rapid prototyping system to fine tune the design and re design the signal flow to meet above needs. It is 5 stage development Tool where user can design graphically Generate Code build & Run Tune on Fly automate the Testing Ship the product

  2. It has the rich set of the inspectors to tune the system

  3. Field proven and well defined host communication and tuning protocols over Serial peripheral interface(SPI), two wire interface (I2C) , UART and Ethernet / WiFi
