How Do Wake Words Differ from Regular Speech Commands?

Wake words and regular speech commands serve different functions in voice recognition technology, and they differ in terms of purpose, processing, and usage:

1. Purpose:
Wake Words: Their primary purpose is to activate the voice assistant or device. They trigger the system to start listening for further inputs.
Example: "Hey Siri," "Alexa."

Regular Speech Commands: These are the actual instructions the user gives after the wake word has activated the device. They direct the assistant to perform specific tasks.
Example: "Set a timer for 10 minutes," "Play music."

2. Processing:
Wake Words: The system constantly listens for wake words with lightweight processing. This happens in the background to avoid draining resources until the wake word is detected.

Regular Speech Commands: Once the wake word is detected, more intensive speech recognition kicks in to understand and execute the commands. These commands require deeper processing and context understanding.

3. Usage:
Wake Words: Used to "wake up" the system or switch it from a passive state to an active state.

Regular Speech Commands: Used to instruct the system to perform specific actions, such as controlling devices, retrieving information, or completing tasks.

4. Activation:
Wake Words: Only wake words are designed to activate the system.
Regular Speech Commands: These only function once the system is activated by a wake word.

In summary, wake words are activation triggers, while regular speech commands are the functional instructions given after activation. Both are essential for smooth interaction with voice-activated systems.
