Specialist speech and language therapy for people with Down syndrome

Hello, and welcome! I'm Tracy, a Speech and Language Therapist specialising in support for people with Down syndrome and their families. I'm newly qualified as a therapist, but bring over 20 years of specialist expertise as a teacher and practitioner — including Master's research on speech and communication in adults with learning disabilities (including people with Down syndrome), and a PhD focused on Down syndrome speech intelligibility, voice, and the use of music to support speech perception and production.

I currently offer three services for children and adults with Down syndrome, within Lincolnshire, that complement current NHS SLT provision.

Three services for Down syndrome

1. Early Communication & Language (Birth to Preschool)

Babies with Down syndrome benefit from support in their first year. I offer parent/carer coaching from birth — whole-communication support for babies and young children with Down syndrome, covering early interaction, speech sounds, and vocabulary and grammar foundations. Working with you, I can develop a therapy programme to help your child meet their next communication steps, and give you the tools and the confidence to deliver the therapy at home, every day.

2. Speech Intelligibility (Throughout School & Beyond)

Speech therapy for children, young people and adults with Down syndrome whose speech is difficult to understand — from school age right through to adulthood. A musical approach works well here to support clear production of sounds and words, as well as perception.

3. Voice Therapy for Down syndrome

Specialist voice assessment and therapy for people with Down syndrome. I draw on my research and clinical experience in voice, singing and communication to support confidence, workplace communication and long-term independence. I can combine traditional voice therapy exercises with singing activities to ensure therapy remains motivating and engaging.

I also offer:

  • a small number of places to preschool children who have speech sound disorders or are at risk of these — for example, those with cerebral palsy, or a sibling with a speech disorder.
  • group music-based communication sessions for adults with learning disabilities and communication needs. Learn more →

Sessions are face-to-face, in your home or educational setting. Some services — parent coaching for babies and voice therapy — may also be suitable online, or as a blend of home visits and online sessions.

Music as a tool in communication therapy

Music isn't used simply to make sessions enjoyable. When included as part of therapy, it may be used to support listening and speech perception, auditory discrimination, rhythm and timing, syllable structure, speech production, sequencing, prosody, intelligibility, and vocal practice.

Where I use music, sessions are structured and listening-focused. My approach draws on Patel's OPERA hypothesis — the idea that learning music trains the same fine-tuned skills that speech and language depend on — and on Kodály-inspired principles, which build listening, attention, rhythm and memory through songs, movement and games. For group music and communication sessions, see my Group Sessions page →

An example from practice: singing a song, clapping its rhythm, reading colour-coded notation, then playing it on bells.

Skills involved: phonological awareness · rhythm at phrase, word and speech-sound level · auditory-verbal memory · sound-symbol correspondence · pitch discrimination · sequencing · vocal and breath control

Rhythm & Timing

Attention to rhythm in music supports attention to rhythm in speech.

Listening & Sound

Musical engagement builds awareness of sounds, patterns and speech.

Turn-taking & Connection

Musical interaction creates natural opportunities for shared attention and exchange — from early back-and-forth play in young children to conversational turn-taking in older children and adults.

Confidence & Voice

Music makes communication enjoyable — and enjoyment builds confidence to try.

Tracy Jeffery, PhD,
Speech & Language Therapist

I came to speech and language therapy through an unusual route. Long before becoming an SLT, I worked with children and adults with learning disabilities, using music to support communication. I became fascinated by how powerful music could be as a motivator for speech and interaction, particularly for people who found spoken communication difficult.

This led to a PhD exploring music, communication and Down syndrome, and to 14 years teaching and researching across Education, Psychology and SEND in higher education. Alongside my academic career, I trained as a speech and language therapist, qualifying with distinction in 2026. I am registered with the HCPC and a full member of the RCSLT, and currently work part time as an SLT within an NHS voice service.

My published work spans voice and communication in Down syndrome, auditory processing, the relationship between music and speech, and voice in hypermobility spectrum disorders. My current practice draws specifically on my specialisms, combining evidence-based speech and language therapy with music, rhythm and singing where these are clinically useful. Read more about the research behind this approach →.

Whether using musical approaches or more traditional SLT approaches, my aim is to make therapy relevant to everyday life, to build on strength and success; and to give parents/carers practical ways to support their child's communication between sessions.
