Alexa and Google Assistant smart speakers were innovative and delivered a quality user experience to the users and it was a really great product at the end. To support such a high performing application engine and get quality input which can decide on the accuracy of the output that user requires could be crucial with a product as Amazon Alexa or Google Assistant because unlike other products, smart speaker could be only get the input via audio signals.

Qualcomm Snapdragon 845 chipset uses the most advanced commercial mobile chip computational power and analytics power in the build. There are new components in built to the chip where developers can access to quality data to offer an outstanding user experience to the users.

You definitely have used Google Assistant on your phone, if your phone is built with Snapdragon 845, your voice commands should be more clear and more understandable for the applications that you are interacting with. At the moment the 20 percent of the daily queries made up by voice commands.

In the solution that Qualcomm provided with the Snapdragon 845 chipset with Qualcomm Aqstic Codec, there are three major components which helps to carry out the operations. And these hardware level components helped Operating Systems and Applications to get the data which needed to process quality decisions.

Analog-To-Digital Converter (ADC) Component

Every time when a person talks or when a machine talks they are emitting sound waves which does have the characteristics of a analog wave. Analog waves needs to be converted to a media that microchips can understand. That's what exactly does by the component which is in the Analog to Digital Converter with high accuracy and high efficiency with low power consumption.

Direct Stream Digital (DSD) Component

Direct Stream Digital or DSD is a component in Snapdragon 845 chipset which is keep streaming the digitally converted audio by the Analog to Digital Converter or ADC component and make the audio available to used by the Digital Signal Processor or DSP component. 

Digital Signal Processor (DSP) Component

Digital Signal Processor is the component which is in the Snapdragon 845 chipset which carry out the process of processing digital signals which received by the ADC also known as Analog to Digital Converter. Digital Signal Processor is capable of enhancing the digital audio which came to the component even though the audio signals are in low quality up to a certain extend. Digital Signal Processor gets help from the Snapdragon voice UI technology to process and analyze the digital audio signals.

Digital to Analog Converter (DAC) Component 

Digital to Analog Converter also known as DAC component in Snapdragon 845 chipset is capable of concerting digitally processed signals to analog and sent out via the Direct Stream Digital or DSD Component to the speakers where user can hear it.

Below figure explains how the Qualcomm processing your voice input and helps the applications to use your voice to provide efficient and accurate assistant on your workflow.



In the build of technology architecture Qualcomm has provided a cutting edge solution where the applications and users gain superior access and quality processing when using the virtual personal assistant.
