Ultrasound Tongue Imaging for Visual Biofeedback

BACKGROUND

This project is using real-time ultrasound images of the tongue as a visual bio-feedback (U-VBF) technique to treat childhood speech sound disorders (SSDs).

SSDs occur when children fail to acquire the speech sounds of their native language in the course of normal development, producing certain sounds incorrectly, substituting them for other sounds or omitting them. Around 6.5% of all UK children have primary SSDs, where the cause is unknown. In addition, speech difficulties are a hallmark characteristic of many disorders such as hearing impairment; Down syndrome; cleft lip and palate; traumatic brain injury and cerebral palsy. Whatever the cause, a difficulty in producing clear speech can have profound effects socially and educationally. Even mild impairments affecting single sounds can have a negative effect on the way children are perceived by their peers.

Traditionally, interventions for SSDs rely on auditory skills, clients must listen to their own productions and modify them using auditory cues. This is difficult for children for whom auditory skills are weak, but teaching children new articulations (i.e. an articulation which they have not acquired naturally) using verbal descriptions alone is cumbersome and problematic, because speech movements are complex and largely invisible. An alternative method, visual biofeedback (VBF) of the tongue, works much in the way that a simple mirror provides VBF of the lips. When people with SSD are enabled to see their own attempted articulations in real time, therapy outcomes are improved. By placing a standard medical ultrasound probe under the chin, most of the surface of the tongue in a mid-sagittal (side-on) view is imaged. The ultrasound display is relatively intuitive and costs of ultrasound equipment are falling while analysis techniques are improving rapidly.

During therapy the ultrasound probe is held still with a headset. This allows the therapy to be “hands-free” and allows us to record the child’s tongue movements as they are happening and interpret them meaningfully.

The surface of the tongue appears as a white line. It moves in real-time and children are easily able to learn to the relationship between the image on the screen and their own tongue movements.

We will evaluate the success of U-VBF therapy for 20 children (aged 6 to 15) with intractable speech sound disorders.

Presentations and Conferences

The UltraPhonix project does not include conference costs, so these presentations to the academic research community are funded with the support of CASL, external bodies, and the staff themselves.

Papers have been accepted for presentation at , Canada, June 2016, and both Zoe Roxburgh and Joanne Cleland (Clinical Lead and co-investigator on the project, now at Strathclyde) will attend, with other researchers from CASL.

Two poster presentations were given by Proj James M Scobbie at ULTRAFEST, in Hong Kong, December 2016.��

Highlights

The Royal College of Speech and Language Therapists () is a co-founder of the International Communication Project (). The ICP advocates and campaigns for those with communication disabilities, as well as their families, caregivers and communication professionals. They have chosen (June 2016) the UltraPhonix project as one of their special features "Stories 17�Թ��� Communication" under the title , featuring Rosie and Zoe pictured with a next generation tablet-based clinical ultrasound system.

The project featured on STV news (12 May 2016) with one of our clients in his first session. We hope to upload a recording of the demonstration later. See also press coverage and links, below.

Science Outreach

Professors Jim Scobbie and Alan Wrench have been invited to a "twilight science" / "Society Lates" from 6pm-10pm at the Royal Academy's Summer Science Exhibition 2016, in London on July 4th. Free, no booking, but adults only []. Prof Jim Scobbie and colleagues at Glasgow University were demonstrating an ultrasound scanner at Kevingrove as part of the Glasgow Science Festival on 11 and 12 June. It was great to see so many enthusiastic people, including some families with children in therapy, and SLTs. In May, "Broken Bodies" at QMU hosted multiple groups of high school pupils and gave them an introduction to Speech and Language Therapy including interactive ultrasound scanning.

CASL has donated an ultrasound scanner to, a home for interactive citizen science, Arts and Science collaborations, and public engagement, at , Edinburgh. Visit ASCUS Lab, or check their schedules and . We were there in person on Tuesday 16th February 2016. This outreach initiative is one of Prof Jim Scobbie's Fellowship activities to help a greater public understanding of the complexities of speech production, accent variation, and Ultrasound-based therapy.

First Minister Visit

Scottish First Minister Nicola Sturgeon and the minister for Education and Lifelong Learning Angela Constance visited QMU on 10th Feb 2016. They met Zoe Roxburgh, the research SLT, Dr Janet Beck, head of Speech and Hearing Sciences, and Prof Jim Scobbie, Director of CASL Research Centre. We explained the reasons for using Ultrasound Tongue Imaging in Speech and Language Therapy, and presented some anonymous examples of successful treatment from the QMU Articulatory Research Clinic - specifically those resulting from the Ultraphonix project. Congratulations to our participants for making such an impact thanks to their hard work with Zoe! You can also see photos also of

There's even a little flash on (1 min 10 secs - 1 min 24 secs) ... blink and you'll miss us. (You can watch it with the sound off if you like - the audio is not very relevant to the project.) So, was that a diagram of YOUR tongue that the First Minister was looking at? Who knows! ��The image shows the front of the tongue surface raising up (in error) towards an attempted /k/ sound. The lower black line is where the consonant begins, and the series of tongue surface tracings (in blue) ends up at the highest thick black tongue surface, in the final position reached. Each blue line is only 8 milliseconds apart, so this shows how fast some parts of your tongue can move, over small distances (just a few millimetres). These sorts of images let us understand more about how speech disorders are produced, which in turn helps us develop better therapies to correct them.

CSO Public Engagement Group

We gave a presentation on the project on 26 November at 11:30 hrs in St Andrews House, Edinburgh, as part of a training day for CSO lay members: "who sit on various CSO grant and policy committees to ensure that the proceedings and decisions taken are discussed are reasonable and fair " - are the funders of this project (ETM/402).
