About this app

Free lite Try-Before-You-Buy version - NO ADS, NO IN-APP PURCHASES

This is Boo!
Boo helps children practice speech sounds that they need to improve. He is designed to entice spontaneous repetition of individual speech sounds and simple syllables. At the same time, he enforces helpful phonological awareness, by showing what actions happen in the mouth during articulation.

The app is developed by a certified Speech-Language Pathologist. The children can use the app all by themselves or together with an adult. When the child simultaneously uses multiple senses (vision and hearing) to imitate and repeat it becomes easier to overcome obstacles and improve its articulation skills.

Who is Boo for?
The app is developed for children aged 3 to approximately 6 years old being in, or need to be in contact with a speech-language pathologist or therapist due to speech difficulties. It provides a motivating way to:
• practice one or more single speech sounds;
• practice voiced contra voiceless consonants;
• practice joining speech sounds together to create simple words;
• practice the link between letters and speech sounds in early reading practice

Boo may be a stepping stone to a better pronunciation!

Boo can also be a helpful pronouncing learning tool for those - young or old - who are currently learning the English language.

Try Before You Buy
This is a free tryout version with speech sounds P B EE AH and limited functionality. However, it should be enough to evaluate how the child interacts with Boo. For example, if the child spontaneously imitates Boo (try the repetition setting!) it may be worthwhile to purchase the paid version.

The paid version contains consonants P B T D K G S Z SH CH F V M N L W as well as monophthong vowels EE AH OO AW ER and full functionality and tips from the SLT.


Boo Articulation Helper is developed by a speech and language therapist & pathologist with therapeutic experience with children with developmental verbal dyspraxia or articulation/phonological impairments. The app is tested by eight children in their homes, aged 3-6 years, seeing a SLT on a regular basis. The try-outs have shown an improvement of training motivation and spontaneous repetition of speech sounds in a way that proved more difficult with other training material and methods (undocumented).

The app is developed to be used on a tablet as it is easier to handle with little children's fingers - although it also compatible with smaller screens.
