How the Voice Command Work in Smart TV Remote Control?
Today, can you imagine that using a TV without a remote control? In the past, there are only four buttons on Television, switch on/off button, volume up/down and channel change keys. Today, so many function keys and the number of buttons in the remote control, which allows us to control the devices from a short distance. However, the remote control could only work when pointing right to the TV or TV box, and it's not very convenient to find out a favorite show quickly, right? This problem is getting more obvious in recent years, as the smart tv or android tv is replacing the traditional televisions. It's time to have a smart remote control to improve the interaction experience between human and television.
The Features of Smart Remote Control
The smart tv could be regarded as another PC, the remote control needs to be smart enough to do a variety of operations. So the voice control, motion and touch control technology is becoming more and more popular in accessing the devices more simple and easier. With voice command, we could speak to find out the favorite tv shows or play a music in a second. Today, let's explore how the voice command works with a smart remote control.
Voice Remote Control Based on BLE
Voice command or search could be implemented by Bluetooth Low Energy (BLE), which is a packet-based protocol, provides a mechanism called channel map update to tackle this problem
Speech is a very powerful and intuitive interface. A short, simple phrase can contain enough information to describe very complex commands. However, capturing a phrase in a noisy environment and deriving a meaningful message, usually as a string, is technically challenging. Fortunately, the issue that created the initial requirement, i.e. the connection of smart devices to the internet, also provides the solution to this complex problem. Devices now have access to cloud computing and can benefit from state-of-the-art voice-to-text recognition engines such as those provided by Nuance Communications, Microsoft, Google, Amazon, and many others. Nowadays, the capabilities of cloud-based speech recognition services are sufficient to provide a very good user experience. New possibilities arise when feeding the voice to the smart device’s virtual assistant. In the last 5 years we have seen a rapid expansion of virtual assistant applications: software agents that perform tasks for an individual. Their capabilities are expanding rapidly with the most widely used being Apple’s Siri, Google Assistant, Amazon Alexa and Microsoft Cortana. Virtual assistants work with text or voice interfaces and use natural language processing to match the text or voice to executable commands. Such applications are already integrated into phones and are rapidly gaining ground in smart speakers, TVs, watches and wearables. Virtual assistants can deliver a wide range of services including providing information, playing music and videos, configuring devices, and even buying items for you.
