Little questions about words with k's
 

My friend is learning Japanese and I've been helping her with some pretty basic stuff. Her boyfriend said that k's should sound somewhere between a k and a g. I've never heard of that and i've been studying for like 2-3 years now, so I was wondering if this is true.

I've never heard anyone say that before...
K's and G's sound almost Identical anyways.
try saying か　and が back to back. It's hard to tell the difference sometimes.
I would just stick with a normal k sound, but I'm no expert.

This is why I'm confused lol. I couldn't give her a clear answer when she asked lol. I basically said "maybe he means like ga and ka sound similar".

yeah. I honestly have no idea what that guy is talking about lol.
I listen to a lot of Japanese podcasts and stuff. And all the K's sound like K's to me....

you sure he didn't mean r's or something?
cause R sounds are kinda a mix between R's and L's as you probably know.

That's the same thing I said to her! I said are you sure he wasn't talking about r's because I know r's kind of are between an r sound and an l.

She said no. The example was Konnichiwa.

Now! the only thing I can think of is where the "kon" part of the sentence originates in the mouth, which is kind of in the back of throat the same where a g would if you were to say gonnichiwa.

I have no idea what you're talking about. They sound nothing the same. What is your native language? That could explain your deficiency.

That's Korean. I know; I've learned it.

Ignore her boyfriend. There's is a difference between a か and a が. That's why the ten ten is there. if they were the same... well, I think you get it.

What do you mean by "between a k and a g"? In English. In Russian?

You can always look at the Voice Onset Time chart and get some basic grasp.

I think that is spoken in Tohoku area.
But "Gonnichiwa" is not used even in Tohoku because this dialect is used when it is not initial letter.
Also sometime たちつてと (ta-chi-tsu-te-to) change to だぢづでど(da-ji-dzu-de-do).

行く（iku）　→　行ぐ（igu）
書く（kaku）　→　書ぐ（kagu）
おとこ（otoko）　→　おどご（odogo）
note; Generally these usages are not used in writing.

FYI;Life in the village of Inakadate

Thank you very much.

k and g sound completely different
 

k pronunce ku. ka ki ku ke ko..i dont understand properly what you are talking about but g can be ga gi gu ge go , we call these "onomatopoeic" of k sound.
we divide k and g properly. got it?:)

No, we don't. Those are just syllables.

Onomatopoeias are words such as どんどん、きゃんきゃん、パラパラ、グングン, etc.

Not "onomatopoeia." がぎぐげご are the [i]voiced[/b] versions of かきくけこ, which are the voiceless velar plosives. Although actually がぎぐげご could be velar fricative or velar nasal rather than a plosive in some dialects for some words. I actually speak like that because I picked it up somewhere when I was in the US before I went to Japan.
