19.54.10 Why is the success rate of finding my phone using voice 
instruction too low? 
The environment noise is large or the microphone's hole is blocked.   
19.54.11 Why can't I use a wakeup keyword fewer than four 
syllables? 
Through the tests, it is found that the success wakeup rate using wakeup keywords with four 
or more syllables is high and the wakeup error rate is low. Therefore, the number of syllables 
is restricted to provide you a better wakeup experience.   
19.54.12 Why does my phone require me to record wakeup 
keywords before using the speech awareness function? 
This requirement is to make your phone better learn your voice features and provide you a 
better speech awareness experience.   
19.54.13 Can I use a more complex voice instruction, for example, 
music or navigation? 
We hope to deeply research and optimize the most common and required voice input 
scenarios. Therefore, currently, we design the voice instructions for making phone calls and 
finding your phone. The instructions for playing music or performing navigation may be 
planned in later versions.   
19.54.14 Why does my phone call a different contact when I input 
voice instructions? 
Currently, the success identification rate can't achieve 100% in the industry. If the 
pronunciations of two contacts are similar, your phone may incorrectly identify the voice 
instruction. The voice identification algorithm engine will be further optimized.   
19.54.15 Why isn't the flash on after my phone responds to my 
speech awareness instruction? 
When the battery level is higher than 20%, the flash is turned on to help you find your phone. 
However, if the battery level is low, the flash is not on to save power.   
19.54.16 Does the speech awareness function consume too much 
power if it is always enabled? 
This function appreciably increases the power consumption if it is always enabled. It does not 
cause obvious impacts on your daily use. Therefore, you can enable it.
