Speech Sounds Visualized is an app designed for speech therapy and English pronunciation learning, with a focus on visualizing “how English speech sounds are formed.” It uses X-ray videos and 3D animations to show internal oral movements, helping users understand tongue placement, mouth shape, and articulation methods for different English phonemes. The product was created by speech-language pathologists and originated from the speech therapy department at Pullman Regional Hospital in Washington State, USA. It launched on the App Store and Google Play in 2017.
In terms of its educational format, it is more of a “pronunciation training tool” than a full course platform. Its main features include selecting sounds to watch X-ray videos, switching to 3D animations, viewing pronunciation explanations written by speech-language pathologists, and using the recording function to practice sounds, words, and sentences. The practice path progresses from individual sounds to sentences, making it suitable for articulation training, English phonetics learning, and university phonetics classroom demonstrations. The main text also specifically mentions that the R-package is helpful for mastering the more difficult /r/ sound.
The product is free to download, but core usage follows a subscription model: $2.99 per month or $29.99 per year; classroom subscriptions require contacting the company for pricing. The trial cost is relatively low for individual learners and therapists, but institutional purchasing budgets require further discussion.
Its advantage is that the visualization approach is highly intuitive. Compared with ordinary mouth-position diagrams, X-ray videos better explain the movement of invisible parts such as the tongue and soft palate. Founder Keri Jones has a master’s degree in speech and hearing sciences and more than 25 years of clinical experience, giving the product strong professional credibility. The downside is that the website does not disclose complete information on phoneme coverage, course length, learning assessment, teacher feedback, or certificates. It mainly serves English pronunciation, so native Chinese speakers who need a systematic spoken English course will still need to pair it with other materials.
It is suitable for speech-language pathologists as a therapy aid, English learners correcting their pronunciation, university instructors teaching speech sound formation, and children or adults who need repeated practice on specific sounds. Access from mainland China and app store download availability are not stated in the main text, so they are currently rated as unknown. If using it in China, it is recommended to first confirm availability on the App Store/Google Play and the available subscription payment methods.
