When it comes to hearing health, few tools are as visually intuitive and informative as the speech banana audiogram. This simple yet powerful concept helps illustrate which sounds are essential for understanding speech—and how hearing loss can impact our ability to communicate. Whether you're exploring hearing care for yourself or a loved one, learning about the speech banana can offer valuable insights into how we hear, what we might be missing, and how audiologists use this tool to guide treatment. In this article, we’ll break down what the speech banana is, how it works, and why it matters for your hearing health.
The "speech banana" is a visual tool used in audiology to represent the range of sounds that are crucial for understanding human speech. On an audiogram—a graph that shows hearing sensitivity across different frequencies—the speech banana appears as a curved, banana-shaped area. This region includes the most common sounds of spoken language, such as vowels and consonants, and typically spans frequencies from about 250 Hz to 4000 Hz. Audiologists use this concept to help patients understand which sounds they may be missing due to hearing loss and how it affects everyday communication.
If you’ve noticed difficulty following conversations or hearing certain sounds, it might be time to check your hearing. A simple hearing test can reveal whether you're missing key speech frequencies—and help you take control of your hearing health.

An audiogram plots sound frequency (pitch) on the horizontal axis and sound intensity (loudness) on the vertical axis. The speech banana overlays this graph to highlight where speech sounds fall. For example, vowel sounds like "a" and "o" are lower in frequency and louder, while consonants like "s," "f," and "th" are higher in frequency and softer. If a person’s hearing thresholds fall outside the speech banana, they may struggle to hear certain speech sounds clearly. This tool helps audiologists tailor hearing solutions—like hearing aids or cochlear implants—to restore access to the full range of speech.
Speech banana sounds are the specific speech frequencies and intensities that fall within the banana-shaped region on an audiogram. These include the most commonly used phonemes in spoken language—vowels and consonants that make up everyday conversation. Examples include:
These sounds are essential for speech clarity and understanding. Missing even a few of them due to hearing loss can make words sound incomplete or confusing, especially in noisy environments.
You might be missing key speech sounds—those that fall within the speech banana, the zone where communication comes to life. Take control of your hearing health today.

The speech banana typically covers frequencies from 250 Hz to 4000 Hz, which includes the essential sounds for understanding spoken language. Here's a breakdown:
This range is critical for speech clarity. Even mild hearing loss within this zone can lead to misunderstandings, especially in noisy environments or group conversations.
Reading a speech banana audiogram involves understanding how sound frequency and intensity are plotted. Here's how to interpret it:
If a person’s hearing thresholds (marked as points or lines on the audiogram) fall below the speech banana, they can hear those speech sounds. If the thresholds are above or outside the banana, those sounds may be inaudible without assistance. Audiologists use this visual to explain which sounds are affected and how hearing aids or other devices can help fill in the gaps.
Additionally, Australia is home to innovative tools like Say Bananas, an AI-powered speech therapy game developed by Say66. It’s designed to support children with speech sound disorders, especially in rural and underserved communities.
Say Bananas is an award-winning speech therapy app developed by Australian researchers at Say66, designed to help children with speech sound disorders (SSD) improve their pronunciation skills through play. Built on over a decade of academic research, the app transforms traditional speech therapy into a brightly themed platformer game, making practice fun, engaging, and effective. Key Features are:

The speech banana is important because it visually represents the sounds that are most critical for human communication. It helps audiologists:
For individuals, understanding the speech banana can be empowering—it reveals how hearing loss affects daily life and highlights the importance of early intervention. By restoring access to the sounds within the speech banana, people can reconnect with conversations, relationships, and the world around them.
The speech banana plays a key role in understanding how hearing loss affects communication. When a person experiences hearing loss, their ability to detect sounds within the speech banana may be reduced or completely absent. This means they might miss critical speech sounds—especially consonants—which can make conversations seem unclear or fragmented. For example, someone might hear the vowel sounds in a sentence but miss the consonants that give words their meaning, leading to confusion. By identifying which parts of the speech banana are affected, audiologists can recommend targeted hearing solutions to restore access to speech and improve everyday interactions.
