![]() ![]() ![]() We can also block airflow by moving the body of the tongue up against the velum, to make the sounds and. But we can pull the velum away from the back of the throat and allow air into the nose. For sounds made in the mouth, the velum rests against the back of the throat. You might also know it as the soft palate. The articulator that you move to allow air into the nasal cavity is called the velum. Make an “aaaaa” vowel again, then make it nasal. When we block airflow in the mouth but allow air to circulate through the nasal cavity, we get the nasal sounds and. We also produce and at the alveolar ridge, and some people also produce the sounds and with the tongue at the alveolar ridge (though there are other ways of making the sound.) If you use the tip of the tongue to block airflow at the alveolar ridge, you get the sounds and. ![]() Before you get to the teeth, you’ll find a ridge, which is called the alveolar ridge. Now from where you have your finger on the roof of your mouth, slide it forward towards your top teeth. English doesn’t have very many palatal sounds, but we do raise the tongue towards the palate for the glide. If you put your finger in your mouth and tap the roof of your mouth, you’ll find that it’s bony. Or we can bring the top teeth down against the bottom lip for and. They don’t do much on their own, but we can place the tip of the tongue between the teeth, for sounds like and. We can also use our lips to block the flow of air completely, like in the consonants and. If you make the sound “aaaaa” then round your lips, the sound of the vowel changes. Let’s start at the front of your mouth, with your lips. This angle gives us a good view of the parts of the vocal tract that are involved in filtering airflow to produce speech sounds. It depicts the inside of your head as if we sliced right between your eyes and down the middle of your nose and mouth. svg by Rohieb [GFDL (), CC-BY-SA-3.0 () via Wikimedia Commons That airflow is then shaped by the articulators. We know that humans produce speech by bringing air from the lungs through the larynx, where the vocal folds might or might not vibrate. ![]()
