Changxing Hotel Intelligent Guest Control, What is the difference between Bluetooth voice system and offline voice system?

connection method

• Bluetooth® voice system: It connects with smart devices through Bluetooth technology, generally the effective connection distance is about 10 meters, and it needs to be within the Bluetooth coverage of the device to work properly. It usually relies on cell phones, tablets and other terminal devices with Bluetooth function to realize voice interaction, for example, guests can use their own cell phones to connect to the Bluetooth voice devices in the hotel room, and then control the room lights, curtains and other smart devices.

• offline voice system: It does not rely on a network or Bluetooth connection, it does the voice recognition and command execution locally on the device. The device has a built-in voice recognition engine and command library, so as long as you speak within the range of voice recognized by the device (usually at a distance of 3 - 5 meters), you can directly control the device without additional connection operation.

speech recognition capability

• Bluetooth® voice system: Voice recognition capabilities often depend on the device to which it is connected and the voice recognition software used. If the connected phone has good performance and the installed voice assistant software is powerful, the accuracy and speed of voice recognition will be higher. But if the network is unstable or the phone lags, it may affect the voice recognition effect .

• offline voice system: As it is a local recognition, its speech recognition capability is limited by the device's built-in speech recognition algorithm and model, and the amount of vocabulary and types of languages that can be recognized are relatively limited. However, for common control commands, such as "turn on the lights" and "close the curtains", the recognition accuracy can reach a high level after optimization, and is not affected by network fluctuations.

Functional scalability

• Bluetooth® voice system: With the rich application ecology of cell phones or other smart terminals, the function is more expandable. More complex functions can be realized by installing different applications, such as deep integration with the hotel's reservation system and service system, so that guests can directly book breakfast and call room service through voice commands.
• offline voice system: Functions are relatively fixed, mainly centered around the control functions of the device itself, expanding new functions requires upgrading the hardware and software of the device, the development cost and difficulty is high, so the expansion of functions is relatively limited.

stability

offline voice system: It does not rely on external networks and other devices to connect, so as long as the device itself has normal hardware and high stability, it is less likely to fail due to connection problems.

Bluetooth® voice system: Stability is affected by the state of the Bluetooth connection and the devices connected to it. If there are other Bluetooth devices interfering with the surrounding area, or if the connected cell phone has insufficient power or is malfunctioning, it may cause the Bluetooth connection to be interrupted, affecting the normal use of the voice control function.
