/ɑ:/

The /ɑ:/ sound in English is a monophthong, which means it’s a simple, pure vowel sound that does not change quality within the same syllable. Here’s how you pronounce it:

• Position your mouth and tongue: For the /ɑ:/ sound, your mouth should be wide open, and your tongue should be low in your mouth.
• Voicing: The /ɑ:/ sound is a voiced vowel, which means your vocal cords vibrate when you produce this sound. You should feel a vibration if you lightly touch the front of your throat while saying the sound.
• Release the sound: With your mouth and tongue in the correct positions, let your breath flow out over your tongue and through your mouth. The vocal cords vibrate to produce the /ɑ:/ sound.
