Childhood Hearing Loss and Language: The Speech Therapist's Role

Childhood hearing loss and language: what parents should know

Childhood hearing loss is a partial or total reduction in the ability to perceive sound. Because children learn to speak by hearing speech, untreated hearing loss can delay spoken language. The encouraging news: when detected early and properly supported, most children go on to develop language well.

Key point: the earlier the screening and the support, the greater the chances of developing language close to that of other children.

Newborn hearing screening

Newborn hearing screening is a simple, painless and systematic test offered in the maternity unit during the first days of life, to identify permanent hearing loss before a language delay sets in.

In France, it is part of the national newborn screening programme, in which the Haute Autorité de Santé (HAS) plays an active role. The tests use two objective techniques requiring no participation from the baby: otoacoustic emissions and automated auditory brainstem responses. In 2025, the HAS issued new recommendations to harmonise practices. A result that needs confirming does not mean the child is deaf: it simply calls for a further assessment by an ENT doctor.

Degrees of hearing loss

The degree of hearing loss reflects the intensity, in decibels, of the sounds a child can no longer perceive. It is measured by audiometry and largely shapes the care plan. The reference classification (BIAP) ranges from mild to profound: the greater the loss, the harder spontaneous access to speech becomes. Loss may be unilateral or bilateral, conductive or sensorineural; only a medical assessment can determine its type, degree and cause.

The speech therapist's role

The speech therapist supports the deaf child in developing communication and language. Working on medical referral, alongside the ENT doctor and the audiologist, their intervention often begins at diagnosis, before hearing devices are fitted. It covers several complementary areas:

• Auditory education: learning to detect, recognise and then discriminate sounds and speech.
• Spoken language work: vocabulary, grammar, articulation and comprehension.
• Support with hearing aids and cochlear implants: helping the child make sense of new sounds.
• Communication support and parental guidance: showing families how to nurture language every day.

This sits within the wider care of children's language disorders, of which hearing loss is one possible cause. Our speech therapist for children page explains the main reasons for consulting.

Cochlear implants and where therapy fits

Hearing aids and cochlear implants restore access to sound but do not "repair" language on their own: rehabilitation turns a sound signal into understanding and speech. A cochlear implant is generally considered for severe to profound loss when conventional aids are not enough; per SFORL recommendations, the indication rests on a multidisciplinary assessment. Whatever the device, speech therapy is the essential complement.

Warning signs and when to consult

Some signs warrant a medical opinion: a baby who does not startle at loud noises; a one-year-old who babbles little or does not respond to their name; a two-to-three-year-old with delayed, hard-to-understand speech; an older child who often asks for repetition or turns up the volume. At the first doubt, consult a doctor, who may refer to an ENT specialist. A speech and language assessment, carried out on referral, evaluates language and sets the goals of care. Where distance complicates access, some sessions may be offered by speech therapy teleconsultation. For professionals, tools such as Cabdivin and AI-assisted speech therapy help structure assessments and track progress.

Frequently asked questions

At what age can a baby's hearing be screened?

From the first days of life, in the maternity unit, using objective tests that need no participation from the infant. A result that needs confirming points to a further ENT assessment rather than a diagnosis.

Will my child's hearing loss permanently prevent language?

No. With early detection, suitable hearing devices and regular speech therapy, many children develop spoken language. The outlook depends on the degree of loss and how early care begins; only a medical assessment can give a personalised view.

Does the speech therapist intervene before or after fitting devices?

Both. Support often begins at diagnosis and continues after hearing aids or an implant are fitted.

Is a referral needed to see a speech therapist?

Yes. Speech therapy requires a doctor's referral, and hearing loss is first diagnosed by an ENT specialist.
