What is voice input on Android?

Voice input allows Android users to dictate speech which is then converted into text. This technology enables hands-free typing and text input through the device’s microphone. Android phones come with built-in voice typing capabilities through Google Voice Typing. Users can activate voice input to write texts, emails, notes, and more just by speaking. The speech recognition can function offline without an internet connection in some cases. Voice input provides an accessible and convenient way to input text quickly on Android devices.

Activate Voice Input

To enable voice input on an Android device, first open the Settings app and go to System > Languages & input. Locate the Virtual keyboard section and tap on Gboard or whichever keyboard you use. In Gboard’s settings, tap on Voice Typing and turn on the toggle to enable it. You can also go into Gboard while typing and tap the microphone icon to quickly turn on voice typing.

Samsung devices may require granting permission for the keyboard to access the microphone if you haven’t already. Go to Settings > Apps > Choose Default apps > Advanced > Default keyboard and enable Microphone access.

On some devices, you may need to go to Settings > Apps & Notifications > Advanced > Special app access > Voice input and enable the keyboard app such as Gboard.

Finally, open any app where you can enter text like Messages, Notes or Gmail. Tap where you can type text and you should now see a microphone icon. Tap it and you can start speaking to enter text via voice input.

Google Voice Typing

Google Voice Typing allows you to speak into your Android device’s microphone to input text instead of typing. It is powered by Google’s speech recognition technology and is built into Gboard, Google’s keyboard app for Android.

Google Voice Typing can achieve high accuracy by leveraging Google’s constantly improving speech recognition algorithms. Google claims it can recognize speech with 95% accuracy or higher for most users [1]. It supports over 100 languages, allowing users around the world to dictate text by speaking in their native tongue.

Some key features of Google Voice Typing include the ability to use it offline without an internet connection, capitalize words, insert punctuation, and edit typed text by voice. Users can also access it simply by tapping the microphone icon on Gboard.

Offline Voice Recognition

Android has the capability to perform offline voice recognition without an internet connection by downloading language packs. This allows voice typing and commands to work even when offline (“Voice Recognition – Tech for Learning – Library Guides”).

To enable offline voice recognition on Android, go to your device’s Settings app and select Google under Accounts. Then choose Search, Assistant & Voice > Voice > Offline speech recognition. From here you can download additional languages to enable offline recognition (“Offline Speech Recognition in Android”).

Once downloaded, offline recognition will be available whenever an internet connection is unavailable. However, the accuracy may be lower than online recognition. Over time, offline recognition can improve through continued use and learning while offline (“What happened to “offline” voice recogniton?”).

Offline voice recognition allows Android users to still utilize voice typing and voice commands even without an internet connection. However, for the most accurate and optimal experience, an internet connection is recommended.

Voice Commands

Android includes built-in voice commands that allow you to perform common tasks like calling, texting, emailing, and getting directions using your voice only. Here are some common voice commands:

For calling and texts:

  • “Call [contact name]” – calls a contact
  • “Send a text to [contact name]” – sends a text message to a contact
  • “Redial” – calls the last dialed number

For emails:

  • “Email [contact name]” – starts composing an email to a contact
  • “Send email to [contact name] – sends an email to a contact

For navigation:

  • “Navigate to [location]” – provides directions to a location
  • “Show me nearby [type of place]” – searches for nearby places like restaurants, gas stations, etc.
  • “Take me home” – provides directions to your home address

These are just a few examples of the many voice commands available on Android. The capabilities depend on your device model and OS version. Check your device settings for available voice commands.

Third-Party Apps

While the built-in Google Voice Typing works well, there are also several excellent third-party voice input apps available for Android. One of the most popular and powerful options is Dragon Dictation, from Nuance Communications. Dragon uses advanced speech recognition technology for high accuracy and allows you to dictate documents, emails, texts, and more. It has powerful voice command capabilities, customization options, and support for over 30 languages.

Other top third-party voice input apps for Android include Notta, which boasts over 99% accuracy and works completely offline, and Speechnotes, which is designed specifically for taking notes by voice. Many of these apps offer advanced features like autocorrection, hands-free voice commands, and personalization that go beyond the native voice typing in Android.

Third-party voice input apps provide alternatives for those looking for different features, higher accuracy, expanded language support, or options that work offline. Top picks like Dragon Dictation are powerful choices for productivity, efficiency, and accessibility.

Customization

There are a few ways to customize voice input settings and word suggestions on Android devices. In the Voice Input settings, you can select languages, block offensive words, and enable enhanced network recognition for speech in apps (Google Support). To improve recognition accuracy, you can download additional speech packs and accents. You can also calibrate speech recognition to better understand your voice.

To customize word suggestions, you can add words to the personal dictionary so they are more likely to appear as you speak. You can view and delete your custom words in the Voice Input settings. Some devices allow you to train word prediction by rating suggestions as very accurate or not accurate (Komando). Over time, the voice typing should become more tailored to your speech patterns and vocabulary.

Accessibility

Voice input provides significant benefits for users with accessibility needs or disabilities. It allows hands-free control of an Android device without touching the screen. People with limited mobility or motor impairments can rely on voice to open apps, navigate screens, type messages, and more.

Google’s Voice Access app is specifically designed for accessibility. It has customizable voice commands to replace touch gestures like taps, swipes, and typing. Users can say things like “Go home” or “Scroll down” to control the device (Source 1).

Voice Access also supports typing dictation with over 80 languages. It provides real-time transcriptions of what’s on the screen when desired. Overall, voice input gives people with disabilities more independence in using Android phones and tablets (Source 2).

Limitations

Voice input on Android does have some accuracy limitations. According to this Android Police article, the built-in voice input system can struggle with multilingual support and frequently changing the language settings is inconvenient. There are also complaints that Google’s voice typing has become less accurate after recent updates, as noted in this Android community discussion.

There are also privacy concerns with voice input. Anything you say is recorded and transmitted to Google or another third-party service for processing. Users uncomfortable with this data collection may want to disable voice input features. Additionally, voice input requires an internet connection, so it is unavailable offline.

Accuracy can also vary between different Android devices. According to Android Authority, Pixel phones tend to offer better voice typing capabilities than other devices. So your experience may depend on which Android phone you are using.

Future Outlook

Looking ahead, experts predict major advances in the natural language processing capabilities of voice input. Some key forecasts include:

Multilingual models: By 2030, speech recognition will likely feature truly multilingual models that support fluent interactions in multiple languages (The Future of Speech Recognition: Where Will We Be in 10 Years?). This could open up voice input to many more global users.

Personalized experiences: Voice assistants may utilize personalization and contextual awareness to deliver tailored responses and predictive capabilities aligned to individual users (10 Key Predictions for the Future Of Voice Assistants).

Integrations for more sophisticated systems: Voice recognition is predicted to integrate with other tools like machine learning and AI to enable more nuanced conversations and complex voice-driven applications (The future of voice recognition: Predictions for the next decade).

Overall, the next decade should see dramatic improvements in the natural language processing power behind voice input, leading to more seamless, intuitive and smart voice interactions across languages and contexts.
