Cued Speech vs. Sign Language: Key Differences and How to Choose

Cued Speech and sign language both turn communication into something you can see, so they are often mentioned together. They are not two versions of the same thing. Cued Speech is a visual system for showing the sounds of a spoken language. A sign language, such as American Sign Language (ASL), is a complete language of its own. Which one fits depends on the people involved, the language they want to use, and the setting. That setting increasingly includes a webcam.

The short answer

Cued Speech pairs hand shapes, placed at set positions near the face, with the natural mouth movements of speech. Many speech sounds look identical on the lips, and the cues make them distinguishable. Because it represents the sounds of a spoken language, the language being cued is still English, or whatever spoken language is in use, with its normal grammar and word order.

ASL is a natural language with its own vocabulary and grammar, separate from English. It uses handshapes, movement, location, facial expression and body position to carry meaning. You can communicate fully in ASL without speaking or mouthing English at all.

Clearing up terms that change the comparison

• "Sign language" is not one language. ASL is the main sign language in the US. Other countries have their own sign languages, and they are not mutually intelligible by default.
• Signed English systems are a different category. Signed Exact English and similar systems borrow signs to follow English word order. They are manually coded English, not ASL and not Cued Speech.
• Cued Speech is not fingerspelling. Fingerspelling spells words letter by letter. Cueing shows sounds syllable by syllable, alongside the mouth.
• The two can be used together. Some families and programs use both, choosing one or the other depending on the person and the situation.

Side-by-side comparison

Aspect | Cued Speech | Sign language (e.g., ASL)

What it is | A visual system representing the sounds of a spoken language | A complete natural language

Language conveyed | The spoken language being cued, such as English | The sign language itself, with its own grammar

Relies on lip movements | Yes; cues are designed to be read together with the mouth | No; mouth movements and facial expressions carry grammar and meaning, but there is no dependence on spoken-word lip shapes

What the hands show | Sound groups at positions near the face | Words and concepts across a wider signing space

Community and culture | Used mainly by families, schools and individuals choosing it | Tied to Deaf communities and Deaf culture

Who can understand it | People who have learned to read cues | People who know that sign language

Choosing by situation

• You want direct access to the sounds and structure of spoken English, such as for literacy or phonics work: Cued Speech is built for that purpose.
• You want to join Deaf community life, events or conversations with Deaf signers: ASL is the language used there.
• You need an interpreter for a meeting, appointment or class: ask which the person uses. ASL interpreters and Cued Speech transliterators are different roles with different training.
• A family is new to hearing loss and deciding where to start: specialists such as audiologists, early-intervention staff, Deaf mentors and educators can explain options. Many families weigh more than one approach.

No outcome data, program details or statistics were available for this article. It does not rank one approach as better overall. That judgment depends on the individual, and qualified professionals and the communities involved are better placed to advise.

Setting up your camera for each on video calls

Both methods depend on the other person seeing you clearly, but they need different things from the frame. Cued Speech depends on the face and the area right around it. Sign language needs room for the hands, arms and upper body.

For Cued Speech

• Keep your whole face in view, especially your mouth, plus the area around your cheek, chin and throat where cues are placed.
• Light your face from the front so your lips are not in shadow. A bright window behind you can turn your face into a silhouette.
• Keep the camera roughly at eye level so your mouth is not seen from a steep angle.
• Avoid anything that covers the mouth, such as a microphone, a hand resting on your chin or a face mask.
• If the person reading your cues also relies on any residual hearing, audio still matters. Check the microphone input separately from what you hear through speakers or headphones.

For sign language

• Frame from roughly the top of your head down to your waist, with space on both sides for your hands. Sit back from the camera rather than leaning in.
• Keep your face clearly lit. Facial expression is part of the grammar.
• Wear a top that contrasts with your skin tone. A plain, uncluttered background makes your hands easier to follow.
• Turn off auto-framing or face-tracking features if they crop out your hands or keep zooming while you sign.

Backgrounds and effects

Virtual backgrounds and background blur in call apps work by guessing where your body ends. Fast hand movements can be partly erased, blurred or smeared by these effects, which matters for both cueing and signing. A real, plain backdrop such as a solid wall or a sheet avoids that problem. This is a different choice from editing the background of a photo afterward, which does not affect a live call.

What a camera check does and does not tell you

Your local preview shows framing, lighting and whether effects are clipping your hands. It cannot show what the other person receives. Call apps may compress video or lower the frame rate on a weak connection, and fast hand movements can blur on the far end even when they look sharp on your screen. The most reliable test is a short call with someone who uses the same method, where you ask them whether your cues or signs are clear. Also check that your browser or operating system has given the call app permission to use the camera, since a blocked permission can look like a broken webcam.
