Bigmouth helps children learn the speech sounds for spoken English. Bigmouth is a friendly cartoon character that gives direct guidance on how to make the sounds correctly. Stories and games make learning fun. It’s designed for kids to play by themselves or with adult guidance.

Bigmouth Sounds v 1.0 includes:
*Quality voice recordings allow children to hear speech sounds and learn to make and discriminate speech sounds. Standard English accent used.

*24 consonant sound character cards and 12 vowels character cards, with all sounds heard in isolation and in words.

*Written and spoken instructions available on how to produce each sound.

*5 fun, sound-based stories that are read aloud to the child with picture scenes. These encourage listening and repetition of sounds.

*Snap game for auditory discrimination work: two spoken sounds are heard and can be repeated, with Bigmouth characters, feedback on success or try again.

*The app has 5 levels to choose from. These levels work up in difficulty in accordance with the recognised developmental order that children learn speech sounds. Level 1 is the easiest. Level 5 is ‘all sounds’.

Bigmouth was originally designed by Speech and Language Therapists Norma Ramsay and Sara Hughes, and has been widely used for many years. Bigmouth has been successful with pre-school children, children with hearing impairment and with learning disability, and also with some adults.

*Bigmouth has a variety of mouth shapes that illustrate the articulatory positions of the lips, teeth and front of tongue.

*A clear distinction is made between voiceless and voiced sounds. The light green colour shows a sound is voiceless (quiet) like ‘s’ and ‘t’, and the dark green colour shows a sound is voiced (loud) like ‘z’ and ‘d’.

*Bigmouth has a nose to show nasal sounds.

*Bigmouth often has an associated item that acts as a visual clue to the sound.

*A selection of 12 vowels is included. Long and short vowels are distinguished by the size of the character.

Could so easily be better

The levels don’t seem to correspond to anything and all sounds appear - it would be so much better if you could select sounds. Same goes for the games - you want to be able to select sounds. Same goes for the stories - it doesn’t say which sounds are focused on. All in all it would have been better just to find the useful pics and descriptions elsewhere and not wasted money.

Good app for engaging children in making sounds

There are 3 different aspects to the app. One is sound cards, where each individual sound is explained and demonstrated. Two is about 5 stories that feature many individual sounds and three is a sound matching snap game.

My young (2.5) son was very interested in the cards, and started trying to make the sounds without any encouragement from me. He also really enjoyed the stories, wanting to listen to them again and again. The narrative voice is friendly and engaging, which I think is what pulled him in. Just for the fact it got him to try making different sounds in a simple yet fun way, it is worth it. Certainly cheaper than most physical card sets and far more interactive.

I am so disappointed in this app. I am a speech and language therapist and bought this as I wanted something for work at single sound level. However you cannot select what sound/s you want to work on. Also the consonant or vowel sound is not written on the card providing no opportunity for phoneme to grapheme matching. No wonder theres no preview as then you wouldn't be fooled into buying it. To cut a long story short don't waste your money.
