What is Voice Control?
Voice control technology allows users to operate devices hands-free using voice commands (Academia source). On a smartphone, voice control enables accessing features and apps through a virtual assistant without touching the screen. Main virtual assistants on smartphones include Google Assistant, Siri on iOS, and Alexa on certain Android devices.
With voice control, users can launch apps, place calls, dictate texts or emails, ask questions, get directions, check information, control music playback, and more using natural voice commands. Virtual assistants use speech recognition and natural language processing to understand commands and complete tasks through voice interactions. This allows for convenient hands-free use of smartphones, especially while driving or multitasking.
Key benefits of voice control on smartphones include accessibility for blind or disabled users, security such as eyes-free authentication, and convenience by minimizing manual interaction with devices. As the underlying speech recognition technology continues improving, voice control is becoming faster, more accurate, and capable of understanding context and complex commands.
Voice Control on Android Phones
The main voice assistant on Android phones is Google Assistant. Google Assistant allows you to use your voice to ask questions, get directions, set reminders, play music, and more. Some of the key capabilities of Google Assistant include:
Checking information like weather, news, sports scores, etc. (https://assistant.google.com/learn/)
Setting alarms, timers, and reminders
Controlling smart home devices
Getting directions or starting navigation
Making calls or sending messages
Asking general questions and getting answers
Playing music, podcasts, audiobooks, etc.
To activate Google Assistant on Android, you can say “Okay Google” or “Hey Google” when your phone is unlocked, or hold down the home button or dedicated Assistant button, depending on your Android device.
Using Google Assistant
Google Assistant allows Android users to control their phones and access information using just their voice. Some of the main features include:
Calling and texting – You can say “Hey Google, call mom” or “Hey Google, send a text to John saying I’m running late.” Google Assistant will make the call or send the text message.
Alarms and calendar – Set alarms by saying “Hey Google, set an alarm for 7am tomorrow.” You can also add calendar events by voice command.
Asking questions – Google Assistant taps into Google’s vast search capabilities to answer your questions. You can ask things like “Hey Google, what’s the weather today?” or “Hey Google, how tall is Mount Everest?”
Controlling smart home devices – If you have smart lightbulbs, thermostats, or other compatible devices, you can say “Hey Google, turn on the lights” or “Hey Google, raise the temperature 2 degrees.” Google Assistant acts as a central hub.
According to Tom’s Guide, some of the most useful voice commands include setting reminders, listening to podcasts, and translating languages.
Customizing Google Assistant
Google Assistant allows users to customize certain settings to personalize the experience. For example, you can change the Assistant’s language and voice by going to the Assistant settings and selecting “Assistant voice” (https://support.google.com/assistant/answer/7544506?hl=en&co=GENIE.Platform%3DAndroid). There you can choose from a variety of voices and accents.
You can also link accounts like Gmail, Calendar, and Photos to have Assistant provide personalized results and actions related to those accounts. Go to Assistant settings > Your data in Assistant > Manage your information. From there you can link new accounts or review permissions. For example, linking your calendar allows you to add events and review your schedule through Assistant.
Additionally, you can teach Assistant to recognize and understand pronunciations for your personal contacts. Go to Assistant settings > Your people > Add people. Type in the name of the contact and how it’s pronounced. This will help Assistant better understand and interact when you request tasks like “Text Mom I’ll be late” or “Call my brother.”
Google Assistant Limitations
Although Google Assistant can be very useful on Android phones, it does have some limitations users should be aware of. One major limitation is that Google Assistant requires an internet connection to function fully. As noted in this Quora article, without a net connection, Google Assistant will not work at all. This means the voice assistant is limited in areas with poor connectivity.
Another limitation is performance differences between budget and flagship Android phones. Google Assistant relies on machine learning and natural language processing which can be resource intensive. Lower-end phones with less powerful chips may experience lagging response times and more misinterpreted requests compared to premium phones, impacting usefulness.
There are also privacy concerns over Google’s data collection through Google Assistant. As users interact with the voice AI, it records and analyzes massive amounts of personal data to improve its services. However, some may find this constant data gathering intrusive or worrisome if privacy protections fail. It’s a trade-off between utility and privacy that users will have to evaluate for themselves.
Alternative Voice Assistants
While Google Assistant is the default voice assistant on Android phones, there are many alternatives users can install and use instead. Some key options include:
The Amazon Alexa app brings Alexa capabilities to Android devices. Users can ask questions, control smart home devices, set timers and alarms, play music, and more. Alexa has a large knowledge base and skill set to draw upon (Source).
Other assistants like Bixby, Soundhound, Sherpa and Extreme Personal Voice Assistant offer similar functionalities to Google Assistant, with some unique capabilities as well. Bixby emphasizes quick commands and can perform vision-related tasks using the camera. Soundhound focuses on music recognition abilities. Sherpa offers hands-free use while driving. And Extreme Personal Voice Assistant works offline without an internet connection (Source).
When comparing the top assistants, factors like speed, accuracy, integration, smart home control, privacy policies and offline use may help determine the right option. Testing different apps to match specific user needs and preferences is recommended (Source).
New and Upcoming Features
Google is continually working to improve and expand the capabilities of Google Assistant. In January 2024, Google announced several changes coming to Google Assistant this year focused on improving quality and reliability.
Some key updates announced include dropping support for underutilized features like setting alarms with media and controlling smart home devices, and focusing more on core capabilities like understanding natural language commands and returning high quality responses.
Looking ahead, advances in AI and natural language processing could enable even more powerful features. Google’s work on large language models like LaMDA point to a future where assistants can carry on more natural conversations. Features like personalized memory, deeper contextual understanding, and multi-turn dialog may become possible.
However, concerns around bias, safety and appropriateness will need to be addressed thoughtfully. Google has emphasized its commitment to developing AI responsibly and testing new capabilities extensively before releasing them.

Voice control on Android phones provides important accessibility features for users with disabilities. Google’s voice control options allow hands-free use of the device without needing to touch the screen. This is especially helpful for those with limited mobility or vision impairments.
One of the main accessibility apps is Voice Access, which allows complete control of the device using voice commands. Users can launch apps, navigate menus, type, edit text, and more using just their voice (Google Support). Voice Access has customizable commands and sensitivity levels to suit each user’s needs.
For those with visual impairments, Android’s TalkBack screen reader can be activated using voice control. By speaking commands, users can hear descriptions of everything happening on screen. This allows for full use of the device without needing to view the display (Google Accessibility Help).
Overall, voice control options like Voice Access and TalkBack enable hands-free phone operation for those requiring accessibility assistance. Voice control provides independence and empowerment to users with disabilities.
Troubleshooting Tips
If you’re having issues with Google Assistant not responding to “Hey Google” commands or not understanding your speech, there are some troubleshooting steps to try:
First, check for microphone or speech recognition problems. Make sure the microphone is not blocked or damaged. Test it by trying to record a voice memo. Clean the microphone area to remove any debris. Also, try adjusting the microphone sensitivity in your phone’s settings. Speaking slowly and clearly can help with speech recognition issues.
You may need to re-train Google Assistant to recognize your voice better. Go to Assistant Settings > Voice Match and delete your existing voice model, then re-record your voice. This will reset and re-learn your voice signature. Check that ‘Hey Google’ voice activation is turned on in Settings.
As a last resort, resetting Google Assistant can help if it becomes totally unresponsive. Go to your phone’s Apps list and select the Google app. In App Settings, choose “Reset app preferences” to reset Google Assistant and wipe any customizations or glitches.
