Siren Whistle
Therapists love the siren whistle as it works on both suck and blow. The siren whistles are 2″ and are the most durable, high quality whistles. This whistle is an excellent tool for speech therapy as it works the muscles around the mouth that help in sound formation. Further, it is practice in cause and effect skills as children blow on the whistle and hear the sound repeated back to them as a whistle.
