Entonasyon ses perdesine göre değerlendirildi.

Değerlendirildi is the passive past tense form of değerlendirmek (to evaluate / assess).

• Active: Birisi entonasyonu ses perdesine göre değerlendirdi.
  = Someone evaluated the intonation according to pitch.
• Passive: Entonasyon ses perdesine göre değerlendirildi.
  = The intonation was evaluated according to pitch.

Turkish uses the passive very naturally when the person doing the action is unknown, unimportant, or not mentioned.

It can be broken down like this:

• değerlendir- = evaluate / assess
• -il- = passive marker
• -di = past tense

So:

• değerlendirildi = was evaluated

This is a very common Turkish pattern:

• yazdı = wrote
• yazıldı = was written
• açtı = opened
• açıldı = was opened

Yes, göre means according to, but in Turkish it comes after the noun phrase it relates to.

So:

• ses perdesine göre = according to pitch

This is normal in Turkish. Many words that function like prepositions in English are actually postpositions in Turkish, so they come after the noun.

Some similar examples:

• bana göre = according to me / in my opinion
• kurallara göre = according to the rules
• hava durumuna göre = according to the weather

Because ses perdesi is a noun compound meaning something like voice pitch or sound pitch.

It is made from:

• ses = sound / voice
• perde = curtain, screen, register, pitch level depending on context
• ses perdesi = pitch

In Turkish noun compounds, the second noun usually takes the third-person possessive ending:

• ses perdesi

When you then add the dative case required by göre, it becomes:

• ses perdesi
  • -ne → ses perdesine

So the full phrase is:

• ses perdesine göre = according to pitch

Because göre requires the dative case.

The base form here is:

• ses perdesi

To say according to pitch, Turkish adds the dative:

• ses perdesi → ses perdesine

The -ne comes from:

• the possessed form perdesi
• plus the dative ending, which appears here as -ne

This happens often with possessed nouns:

• arabası = his/her car

• arabasına = to his/her car

• adı = his/her name
• adına = in his/her name / to his/her name

So perdesine göre is grammatically exactly what Turkish expects.

Yes. -di is the definite/simple past tense in Turkish.

So değerlendirildi means:

• was evaluated
• got evaluated

This tense usually refers to a completed action and is commonly used for factual narration.

It is different from forms such as değerlendirilmiş, which can suggest apparently was evaluated or a result/state depending on context.

Turkish does not have definite articles like English the.

So entonasyon can mean:

• intonation
• the intonation

Which one is intended depends on context.

That is very normal in Turkish. For example:

• Kitap masada. = The book is on the table / A book is on the table
  Context decides.

In your sentence, English naturally uses the intonation, but Turkish simply says entonasyon.

The sentence is natural as written, but Turkish word order is fairly flexible.

Current order:

• Entonasyon ses perdesine göre değerlendirildi.

This is a neutral, standard order:

• topic/object-like element first: Entonasyon
• adverbial phrase: ses perdesine göre
• verb last: değerlendirildi

You could also hear:

• Ses perdesine göre entonasyon değerlendirildi.

This might put slightly more focus on according to pitch.

In Turkish, the verb usually stays at the end, but other parts can move for emphasis or style.

Entonasyon is a loanword, ultimately from a European language source, and it is used in Turkish especially in linguistics, music, phonetics, and speech-related contexts.

It means intonation.

Turkish often uses loanwords in technical or academic language, alongside native Turkish words in other contexts. So seeing a word like entonasyon in a formal sentence is completely normal.

A rough pronunciation guide is:

• deh-yer-len-di-ril-di

A few useful notes:

• ğ in değer usually does not sound like a strong consonant in modern Turkish. It often lengthens or smooths the vowel before it.
• So değer sounds roughly like deh-er or deh-yer, depending on speech and accent.
• The stress in Turkish often falls near the end, but longer words and derived forms can have more complex stress patterns.

You do not need to pronounce ğ like a hard g. That is one of the most common learner mistakes.

Not with the same meaning.

• ses perdesine göre = according to pitch
• ses perdesiyle = with/by means of pitch

These are different relationships.

In your sentence, the intended meaning is that pitch is the criterion or basis for evaluation, so göre is the right choice.

If you used -yle, it could sound more like pitch was the instrument or tool, which is not the usual meaning here.

So:

• ses perdesine göre değerlendirildi = correct for evaluated according to pitch

Because Turkish often leaves things out when they are not necessary.

In this sentence, the passive form already tells us that the important information is:

• what was evaluated: entonasyon
• by what standard: ses perdesine göre

The agent is not important, so Turkish does not mention it.

This is very common in formal, academic, and technical writing. English also does this a lot with passives:

• The samples were analyzed.
• The data were collected.
• The intonation was evaluated according to pitch.

So the Turkish sentence sounds very natural in that kind of style.
