每日口說挑戰睡太多或太少都有事！每天要睡多久才夠？(How much sleep do you really need? | Sleeping with Science, a TED series)

Intro:
Welcome to today's Pronunciation Challenge! I am your host, Mia.
Today's video is about sleep. Talking about sleep, which kind of sleeper are you?
Are you a night owl? The people often stay up late.
Or are you sleepyhead? You can fall asleep anywhere and anytime because you just crave it.
While no matter which sleeper you are, we are all bothered by a question: "How much sleep do I need?"
I have the experience that I feel drowsy for the whole day and just don't feel energetic.
That reason might be that I stay up too late, wake up too early, or am just exhausted that I need more sleep than usual.
But I also experienced that even though I go to bed earlier, like just trying to adjust my circadian rhythm you know, making my lifestyle healthier.
But…I still feel sleepy the next day!
That was really annoying. I want to feel refreshed instead of feeling like a walking dead.
Therefore, to people who might have such problems as me, you can check out this video later. And now, let's see today's sentence!


Sentence
In fact, the Center for Disease Control in the United States, or the CDC, they stipulate a minimum of seven hours of sleep a night for the average adult.

Pronunciation tips
1. stipulate: Let’s separate the word into three parts: sti-pu-late. In the first part, “sti” the vowel “i” is the short i sound, so is /ɪ/. And then in the second part, “pu” the vowel “u” is the /u/ sound. Noticed that there is actually a pronunciation of /j/ between /p/ and /u/. So it sounds like /pju/. And then the last part “late” is /leit/. Combining all together, is [ˋstipjuleit].

2. minimum: Separate the word into two parts: “mini” and “mum.” In British English, people say /ˈmɪn.ɪ.məm/. They pronounce the “i” as /ɪ/ here. While in American English, the word is pronounced /ˈmɪn.ə.məm/. The second i is the /ə/ sound instead of the /ɪ/ sound.
But the second part of the word “mum” is pronounced the same in both kind of English. The “u” is /ə/ sound. So is /məm/. So a quick wrap-up, British English /ˈmɪn.ɪ.məm/, and American English /ˈmɪn.ə.məm/.

3. average: Three syllable, av-er-age. The second syllable is er, /ɚ/. And then the last syllable, “age” is pronounced /ɪdʒ/. So noted that it’s the the /ɪ/ sound here. Combining all together, /ˈæv.ɚ.ɪdʒ/, /ˈæv.ɚ.ɪdʒ/.

Def: to say exactly how something must be or must be done

Def: the smallest amount or number allowed or possible

3. average (a) 平均的 KK[ˋævərɪdʒ] IPA /ˈæv.ɚ.ɪdʒ/

Outro
The amount of sleep and the quality of sleep are both necessary. You can neither sleep too short nor too long. There is a balance in it. As for how many sleeping hours are exactly what we need, you can check out the video and find the answer. I know we all have a busy life; many things need to be finished, and many works make you exhausted. Sometimes we even have nightmares about those jobs and work chasing us.
Therefore, I hope you can at least get some tips about sleep in this video to improve your sleeping condition. It might make you less tired and drowsy.
I am Mia.
