based

Hi,

I wonder the word "based" should be pronounced as "beyst" or "beysd"?

I think the first "t" is correct.

/beɪst/
/beisd/

You're right. English speakers can't easily make a /d/ sound after an unvoiced /s/.

By comparison, "razed" is pronounced /reizd/ with no difficulty.

The -d/ed suffix is pronounced:


/d/ after voiced sounds except /d/,
/t/ after unvoiced sounds except /t/,
/əd/ or /ɪd/ after /t/ and /d/.

[Silverobama]

Hmm, I think "based" with the "t" sound is right here? I don't quite understand "unvoiced sounds".

Let's say "based", "beist", the "s" is pronounced, so it should be voiced, and it should be "beisd".

[Piscean]

/z/ is voiced; /s/ is unvoiced.

If you block your ears when you say this sound, you will hear the buzzing of the vocal cords when you prouce the /z/. It is not there when you produce the /s/.

By comparison, "razed" is pronounced /reizd/ with no difficulty.

I just noticed that I wrote /reisd/ instead of /reizd/ ​in the quoted post. I've corrected my error. Sorry!

I would go with "baste" as in "Don't forget to baste the turkey.

Baste and based sound exactly alike unless the following word starts with a vowel sound. In that case some speakers vocalize the d. In other words their "based on" sounds like "base don" rather than "baste on".

It is a very small difference. You have to listen hard to even notice it.
