Eu falo com respeito.

Yes. In Brazilian Portuguese, subject pronouns are often optional because the verb ending already shows the subject.

• Eu falo com respeito = I speak with respect
• Falo com respeito = also I speak with respect

Including eu can add emphasis, clarity, or contrast, such as:

• Eu falo com respeito, mas ele não.
  I speak with respect, but he does not.

In everyday speech, dropping eu is very common.

Because falo is the first-person singular form of falar in the present tense.

Present tense of falar:

• eu falo = I speak
• você/ele/ela fala = you/he/she speaks
• nós falamos = we speak
• vocês/eles/elas falam = you all/they speak

So if the subject is eu, the correct form is falo.

Com usually means with.

In Eu falo com respeito, it shows the manner of speaking:

• com respeito = with respect / respectfully

So the sentence means that the person speaks in a respectful way.

Portuguese often expresses manner with a preposition + noun structure, where English might use an adverb.

So:

• com respeito = with respect
• natural English translation: respectfully

Portuguese also has adverbs, and you could say respeitosamente, but that sounds more formal and less everyday.

Compare:

• Eu falo com respeito. = natural, common
• Eu falo respeitosamente. = correct, but more formal or stylistically marked

Because com respeito is a fixed, natural expression meaning with respect or respectfully.

Portuguese often omits the article in expressions of manner like this:

• com respeito = with respect
• com cuidado = carefully / with care
• com calma = calmly / with calm

If you add an article, the meaning can shift or sound more specific depending on context:

• com respeito = respectfully
• com o respeito de um filho = with the respect of a son

So in your sentence, no article is the normal choice.

It means I speak respectfully.

That is because com respeito describes how the person speaks, not what they speak about.

If you want to say I talk about respect, you would say:

• Eu falo sobre respeito.

So:

• com respeito = with respect, respectfully
• sobre respeito = about respect

Yes, it is natural and correct.

It can sound a little assertive depending on context, because it suggests:

• I speak respectfully
• I am being respectful when I speak

You might hear it in situations like:

• defending your tone in an argument
• explaining your values
• asking for respectful communication

For example:

• Eu falo com respeito, então espero o mesmo de você.
  I speak with respect, so I expect the same from you.

Sometimes, yes. Portuguese present tense can cover both a general meaning and a current meaning, depending on context.

• Eu falo com respeito. can mean
  
  • I speak with respect in general
  • or, in context, I am speaking with respect

However, if you want to make the ongoing action very clear, Brazilian Portuguese often uses:

• Estou falando com respeito. = I am speaking respectfully / I am speaking with respect

So the simple present is flexible, but estou falando is more explicitly ongoing.

A simple approximate pronunciation is:

• eh-oo FAH-loh kong hes-PEY-too

A few useful notes:

• eu sounds roughly like eh-oo said quickly
• falo has stress on fa
• com often sounds like kong or a nasal kohng
• respeito has stress on pei

In many Brazilian accents, the r at the start of respeito sounds like an English h, so it can sound like:

• hes-PEY-too

Yes, that is grammatically correct.

But there is a difference in style:

• Eu falo com respeito = more natural, everyday, conversational
• Eu falo respeitosamente = more formal, more explicit, less common in casual speech

So if you are learning natural spoken Brazilian Portuguese, com respeito is usually the better choice.

Yes, if you want to emphasize that the action is happening right now.

Compare:

• Eu falo com respeito.
  I speak with respect / I speak respectfully.
  This can be general or contextual.

• Eu estou falando com respeito.
  I am speaking with respect.
  This clearly refers to the current moment.

The second version is especially useful in a disagreement, when someone is questioning your tone.

Yes. In this sentence, respeito is a noun meaning respect.

The structure is:

• com = preposition
• respeito = noun

Together, com respeito functions like an adverbial phrase describing the way someone speaks.

This is very common in Portuguese: a noun phrase can act like an English adverbial expression.

A lot of everyday Portuguese expressions use this pattern:

• com cuidado = carefully
• com calma = calmly
• com carinho = affectionately / with care
• com paciência = patiently
• com atenção = carefully / attentively
• com honestidade = honestly

So Eu falo com respeito fits a very common and useful pattern:

• Eu falo com calma. = I speak calmly.
• Ela respondeu com educação. = She answered politely.
• Eles trataram todos com respeito. = They treated everyone with respect.
