This innovative app harnesses the power of eye-tracking technology, allowing users to compose messages and have conversations using just the movement of their eyes. With the app, users can select pre-written phrases and have them spoken aloud by their device.

This ingenious app empowers individuals who may have difficulty speaking or typing to express themselves fluently and effortlessly. Providing them with a means to express themselves and engage in social interactions.

Look to Speak offers a simple yet powerful solution that empowers non-verbal individuals to communicate effectively and be heard.

The Need for Communication Tools for Non-Verbal Individuals

Communication is a fundamental aspect of human interaction, enabling individuals to express thoughts, emotions, and needs. For non-verbal individuals, however, this essential form of expression can be a significant challenge.

The inability to communicate verbally can lead to feelings of isolation, frustration, and hindered social interactions. In recognizing this need, the development of communication tools specifically designed for non-verbal individuals becomes crucial.

This is where specialized communication tools come into play. These tools bridge the communication gap, empowering non-verbal individuals to express themselves, engage with others, and actively participate in society.

Augmentative and alternative communication (AAC) devices, such as speech-generating devices and communication apps, offer a lifeline to those who cannot rely on verbal communication alone. These tools utilize various methods, including symbols, pictures, and text, to enable users to convey their thoughts and emotions effectively.

These systems allow users to control communication devices or applications using their eye movements, providing a hands-free and intuitive way to communicate.

Google’s Look to Speak app, mentioned earlier, is a prime example of how advanced technology can transform the lives of non-verbal individuals, offering them a voice and the ability to participate actively in conversations.

The need for communication tools tailored to non-verbal individuals goes beyond mere convenience. It is about providing a fundamental human right—the right to communicate.

Accessible communication tools not only enhance the quality of life for non-verbal individuals but also promote inclusivity and understanding in society, fostering a more compassionate and connected global community.

How to Look to Speak Works

Google’s Look to Speak app operates on a remarkably simple yet powerful principle “Eye-tracking technology”. This innovative application empowers non-verbal individuals to communicate using just their eye movements, providing them with a means to express themselves effectively and independently.

Here’s how Look to Speak works;

Eye Tracking Calibration:

When a user launches the Look to Speak app, it first calibrates the device to the user’s eyes. This calibration process ensures precise tracking of the user’s eye movements, allowing the app to accurately interpret their gaze.

Phrase Selection:

The app displays a list of phrases or sentences on the screen. These phrases are typically organized into categories for easy navigation. Users can navigate through the list by moving their eyes, and the phrases they are looking at are highlighted.

Eye Movement Selection:

To select a specific phrase, the user simply focuses their gaze on it for a brief moment. The app detects the direction and duration of the eye movement, interpreting it as a selection command.

Speech Output:

Once a phrase is selected, the app vocalizes the chosen words or sentence, allowing the user’s thoughts to be expressed verbally. This spoken output enables the user to communicate their needs, thoughts, or responses to others in real time.

Customization and Personalization:

Look to Speak is designed with customization in mind. Users can personalize the app according to their preferences. This includes adjusting the sensitivity of eye tracking, changing the language and voice output, and organizing frequently used phrases for quick access. This customization ensures that the app caters to the specific needs of each user.

Hands-Free Operation:

One of the significant advantages of Look to Speak is its hands-free operation. Users do not need to touch the device or use their hands to communicate. This feature promotes independence and allows individuals with limited motor skills to use the app effectively.

The Role of Machine Learning in Look to Speak

Machine learning plays a crucial role in the functionality of Look to Speak. The app uses machine learning algorithms to analyze and interpret the user’s eye movements, allowing it to accurately detect which phrase they are looking at. This technology enables the app to adapt to each user’s unique eye gaze patterns, improving accuracy and responsiveness over time.

The benefits of machine learning in assistive technology are significant. This technology allows for personalized experiences designed for each individual user, enhancing their ability to communicate effectively.

Personalizing Look to Speak for Individual Users

Personalizing Look to Speak is a key aspect of its design, ensuring that the app caters to the specific needs and preferences of individual users.

Here’s how Look to Speak can be personalized for each user;

Custom Phrases and Vocabulary:

Look to Speak allows users to add custom phrases or vocabulary that are relevant to their daily lives. This feature ensures that users can communicate about specific activities, places, or people that are important to them.

Language Selection:

Users can choose the language in which they want to communicate. This feature is particularly useful for multilingual users or those who are more comfortable communicating in a specific language.

Voice Selection:

Look to Speak offers a variety of voice options. Users can select a voice that they find most comfortable and reflective of their identity, ensuring that their communication sounds natural and personalized.

Eye-Tracking Sensitivity:

The sensitivity of the eye-tracking feature can be adjusted based on the user’s comfort level and eye movement capabilities. Some users may require more precise tracking, while others may need a broader range for effective communication.

Frequently Used Phrases:

The app allows users to save and organize frequently used phrases for quick access. This customization feature enables users to communicate more efficiently, especially in situations where a rapid response is needed.

Colour and Text Size:

Look to Speak offers options to customize the colour scheme and text size. Users can choose colours that are visually comfortable for them and adjust text size for better readability, enhancing the overall user experience.

Training and Calibration:

The app provides a training and calibration process where users can fine-tune the eye-tracking system to match their natural eye movements accurately. This calibration ensures the precise selection of phrases, making communication smoother.

Look to Speak allows users to design to their unique communication style. Non-verbal individuals can convey their thoughts and emotions more accurately, fostering better understanding and connection with others.


As Google continues to push the boundaries of assistive technology, we can only imagine the transformative impact this innovation will have on the lives of countless people. Google Look to Speak has the potential to inspire further innovation in assistive technology, driving advancements that will continue to break down barriers and create a more inclusive society for all.
