Generally speaking, the multimedia systems used in cars have wake-up words. During driving, you can activate the voice assistant by using the wake-up word, and then operate some functions of the car through the voice assistant. After activation via voice, you only need to give commands to the voice assistant. There are many types of keywords included in the voice commands, which can control the car's navigation, music, air conditioning system, etc. The Lamando is equipped with a multifunction steering wheel. If you want to activate it via voice, you can do so through the buttons on the steering wheel or directly via voice commands. Additionally, you can make phone calls in the car through the voice assistant, which is very convenient for the driver and can also improve driving safety. It should be noted that the application of in-car navigation voice recognition technology often operates in noisy environments. If the noise inside or outside the car is relatively loud, it can greatly affect the accuracy of voice recognition, potentially leading to misjudgments by the voice assistant. Therefore, noise is a crucial factor affecting the accuracy of the voice recognition system, posing a significant challenge to voice recognition technology.

I recently picked up my new Lamando, and I've practiced the voice wake-up feature several times. Just say "Hello, Lamando" directly to the center console to activate the system. While driving, if I suddenly want to adjust the temperature or switch songs, I don’t need to take my hands off the wheel to press the screen—super convenient. The first time I tried it, I was waiting at a traffic light and it took three attempts to wake it up successfully. I realized it works best in a relatively quiet environment inside the car. Now I’ve learned my lesson: roll up the windows to reduce tire noise, speak slightly closer to the microphone, and enunciate clearly—it works almost every time now. After activation, you’ll hear a prompt tone, and you have two seconds to give a command before it goes back to sleep. I often use it to open or close the sunroof and set navigation, especially when it’s raining and visibility is poor—voice control really saves the day.

Last week, I took my dad to experience my new car. He shouted 'Lingdu, hello' at the steering wheel, but got no response. I quickly demonstrated the correct wake-up phrase 'Hello, Lingdu,' teaching him to enunciate these four words clearly. Later, I noticed the microphone icon on the steering wheel button area and pointed it out, instructing him to speak toward that spot when activating the system. Now, the old man gets in the car and immediately commands it to play crosstalk, even summarizing his experience: the infotainment system responds a bit slower right after startup, so it's safer to wait until the dashboard fully lights up before giving commands. Once, when he said 'open the window' with no response, I checked the manual and realized the system requires complete instructions like 'lower the driver's window'—it's quite rigid in its requirements.

When I first got the car, I couldn't figure out the voice control logic, so I specifically went to the 4S store to ask the technician. He said the Lamando comes standard with a dual-microphone noise reduction array across all trims, and it can be activated as long as the trigger word is precise. The wake-up phrase is fixed as 'Hello, Lamando' and cannot be customized. During actual driving tests, I found that when the speed exceeds 80 km/h, wind noise interference is significant, reducing the success rate to about 60-70%. The technician taught me to use the physical button at the lower left of the steering wheel in combination: pressing the mute button briefly and immediately saying the wake-up phrase has a higher success rate than just shouting it. Later, I discovered a voice training module in the car's system. Following the prompts to read five sets of short sentences can improve recognition accuracy. Now, it can even understand me when I'm speaking with a mask on.

While working as a ride-hailing driver, I often pick up IT professionals. One passenger who studied this voice system mentioned that the wake word 'Lingdu' is designed with double plosive sounds, making it more resistant to interference compared to single-syllable wake words used by other brands. Last time at a red light, he tested the microphone sensitivity and found that speaking near the A-pillar triangle window resulted in a 0.3-second faster response than speaking toward the center console. He also taught me to set up shortcut phrases for common commands, such as replacing 'Navigate to XX Residential Area' with 'Go home.' Recently, I discovered an Easter egg: shouting the wake word toward the sunroof control area yields a higher recognition rate than shouting toward the center screen, likely due to the directional tuning of the in-car microphone.
