Çok seslilik artikülasyonla daha açık duyuluyor.

Çok seslilik is an abstract noun meaning polyphony or multi-voicedness.

It is built from:

• çok = much / many / multi-
• sesli = voiced / having sound / multi-voiced in context
• -lik / -lık / -luk / -lük = a suffix that turns an adjective or quality into an abstract noun

So çok sesli means polyphonic / multi-voiced, and çok seslilik means polyphony as a concept.

In this sentence, çok seslilik is the subject.

It does not need one here because it is the subject of the sentence.

In Turkish, the basic subject form is the nominative, and the nominative usually has no visible ending.

So:

• çok seslilik = the subject, in its basic form
• no extra case marker is needed

Artikülasyonla means with articulation or by means of articulation.

The ending -la / -le is an instrumental/comitative ending. It often means:

• with
• by
• using

So:

• artikülasyon = articulation
• artikülasyonla = with articulation / through articulation

Because artikülasyon ends in a consonant, Turkish uses -la, not -yla.

Compare:

• kalemle = with a pen
• arabayla = by car

This is one of the most important points in the sentence.

• duymak = to hear
• duyuyor = is hearing / hears
• duyulmak = to be heard
• duyuluyor = is being heard / is heard / can be heard

Here, çok seslilik is not the one doing the hearing. It is the thing that is heard. So Turkish uses the passive form:

• duyuyor = someone hears
• duyuluyor = something is heard

So the sentence structure is basically: Polyphony is heard more clearly with articulation.

-yor is the Turkish present continuous marker.

It often corresponds to English:

• is ...-ing
• sometimes simple present, depending on context

So:

• duyuluyor literally looks like is being heard
• but in natural English it can also mean is heard or can be heard

In sentences like this, -yor does not always mean something happening only at this exact second. It can also describe a general observation or current state.

Yes, açık is usually an adjective meaning open, clear, or distinct. But in Turkish, adjectives are often used in ways that English would express with an adverb.

So:

• açık = clear / distinct
• daha açık duyuluyor = is heard more clearly / more distinctly

This is very natural in Turkish. English often requires -ly, but Turkish often does not.

So although açık is not formally marked as an adverb here, the meaning is adverbial because it describes how it is heard.

Daha means more.

It creates a comparative idea:

• açık = clear
• daha açık = clearer / more clearly

So daha açık duyuluyor means:

• is heard more clearly
• sounds clearer
• is more distinct to the ear

Yes, açıkça is possible in Turkish, and it would mean something like clearly or plainly.

So a sentence like: Çok seslilik artikülasyonla daha açıkça duyuluyor would also be understandable.

However, daha açık duyuluyor is very natural and idiomatic. Turkish often uses the adjective directly in this kind of structure, especially with verbs like görünmek and duyulmak.

So:

• açık = very natural here
• açıkça = also possible, but a bit different in tone

Because Turkish normally places the finite verb at the end.

This is the default pattern in many Turkish sentences:

• subject
• other information
• verb

So here:

• Çok seslilik = subject
• artikülasyonla = with articulation
• daha açık = more clearly / more distinctly
• duyuluyor = is heard

That final verb position is one of the most basic word-order features of Turkish.

Yes, Turkish word order is flexible, although the verb usually stays at the end.

For example, depending on emphasis, you might also hear:

• Artikülasyonla çok seslilik daha açık duyuluyor.
• Çok seslilik daha açık duyuluyor artikülasyonla.
  This is less neutral and sounds more marked.

The original sentence is a normal, neutral order. Changing the order usually changes the focus or emphasis, not the basic meaning.

No, it is a loanword, ultimately related to the international word articulation.

In Turkish, it can be used in fields like:

• speech
• singing
• music
• phonetics

So an English speaker may recognize it, but it still behaves like a normal Turkish noun:

• artikülasyon
• artikülasyonla
• artikülasyonu, etc.

Because Turkish does not use articles the way English does.

English needs:

• the
• a/an

Turkish usually does not. Whether something is definite or general is often understood from context.

So çok seslilik can mean:

• polyphony
• the polyphony
• polyphonic texture, depending on context

Turkish leaves that more open unless there is a specific reason to mark it more clearly.

A close breakdown is:

• Çok seslilik = polyphony / multi-voicedness
• artikülasyonla = with articulation / by means of articulation
• daha açık = more clear / more clearly
• duyuluyor = is heard / is being heard

So very literally: Polyphony with articulation more clearly is heard.

Natural English would be: Polyphony is heard more clearly with articulation.
