I attended a speech therapist in India. He had some very helpful excercises. I’ll try to share what I remember: 1. Make a list of short easy words starting with vowels. Examples: ant, apple, elephant, idea, umbrella, obey, old. Make your kid read each word loud and strecth the first letter of each word for 6-8seconds. Like: aaaaaaaaaaaapple. This will help free up his vocal cords and balance the air flow. Try to read 15-20 words every day. 2. Make your kid read his favorite book with these techniques. (You read and make him repeat) In every sentence pause after 3-4 words. After each pause, breath, while releasing the air from mouth, prolong the first syllable (like in point 1) of each word and complete the next 3-4 set of words. This will help him understand not to rush. 3. Every day spend some time making him say his favorite things or super heroes or anything he likes. But always tell him to say the words as slow as possible (like in point 2 above). 4. When going out, encourage your kid to speak to strangers like cashiers (by following above techniques). Make your kid ask questions. This will help build confidence. 5. Most importantly: breathing and releasing the air with mouth while speaking is very important.
