Riconosco la sua voce.

Riconosco is the first-person singular present tense form of riconoscere.

• riconoscere = to recognize
• riconosco = I recognize

So the ending -o tells you the subject is I.

Italian often leaves out subject pronouns when they are not needed.

So instead of saying Io riconosco la sua voce, Italian usually just says Riconosco la sua voce.

That works because the verb form riconosco already shows that the subject is I.

Including io is possible, but it usually adds emphasis, like:

• Io riconosco la sua voce = I recognize her/his voice

Sua is a possessive adjective. Here it means:

• his
• her
• sometimes your in the formal singular sense

So la sua voce can mean:

• his voice
• her voice
• your voice if speaking formally

Italian often does not tell you the gender of the owner through the possessive. You usually need context to know whether it is his or her.

Because Italian possessives agree with the thing possessed, not with the owner.

Here, the possessed noun is voce:

• voce is feminine singular
• so the possessive must also be feminine singular
• therefore: sua

Compare:

• la sua voce = his/her voice
• il suo nome = his/her name
• le sue mani = his/her hands

The form changes to match voce, nome, mani, etc.

In Italian, possessives are usually used with the definite article:

• la sua voce
• il mio libro
• le nostre case

So la sua voce is the normal form.

Italian usually omits the article only in some special cases, especially with singular close family members:

• mia madre
• tuo fratello
• suo padre

But voce is not a family noun, so the article stays:

• la sua voce

La is the feminine singular definite article, meaning the.

It goes with voce because:

• voce is feminine
• voce is singular

So:

• la voce = the voice

In this sentence, la sua voce is the direct object of the verb riconosco.

This is the most neutral and common Italian word order:

• verb + object

So:

• Riconosco = I recognize
• la sua voce = her/his voice

Italian can change word order for emphasis, but this version is the standard, natural one.

For example, a more emphatic structure might be:

• La sua voce la riconosco

But the plain, everyday sentence is:

• Riconosco la sua voce

This is a very common learner question.

• conoscere = to know, to be familiar with, to know a person/place
• riconoscere = to recognize

Examples:

• Conosco Maria = I know Maria
• Riconosco Maria = I recognize Maria

So in your sentence, riconosco means that the speaker identifies the voice as familiar.

A simple pronunciation guide is:

ree-ko-NO-sko la SOO-a VO-che

A few notes:

• ci before o in riconosco is a hard k sound because it is co, not ce/ci
• sua is usually pronounced in two syllables: SU-a
• voce ends with -ce, pronounced like che in chess

A rough IPA pronunciation is:

[rikoˈnosko la ˈsu.a ˈvo.tʃe]

The present tense in Italian can sometimes overlap with English simple present and present progressive, depending on context.

So Riconosco la sua voce most naturally means:

• I recognize his/her voice

But in the right situation, it could also imply something like:

• I’m recognizing the voice
• I can tell whose voice it is

Still, the most straightforward interpretation is the simple present: I recognize his/her voice.

Yes. Voce is a feminine noun in Italian.

That is why you get:

• la voce
• una voce
• questa voce
• la sua voce

Even if the voice belongs to a man, the noun voce itself is still grammatically feminine. Grammatical gender and real-life gender are not the same thing.

Yes, that is grammatically correct.

But io is usually unnecessary unless you want emphasis or contrast.

For example:

• Io riconosco la sua voce, ma tu no. = I recognize her voice, but you don’t.

Without emphasis, Italian normally prefers:

• Riconosco la sua voce
