Ever since I started learning Latin, I had a question: how did the Romans pronounce Latin? Not the word, but the language in general. To make it easier for you to answer, please compare their pronunciation to that of a modern civilisation.
Instead of giving a pronunciation guide here, let me point you to some resources that should get you started. The topic is very broad and I doubt I could give sufficient instructions within an answer of reasonable length.
First, let me point out that we know fairly well how the Romans pronounced Latin. Many present-day Latinists, including myself, try to pronounce Latin as the ancient Romans did.
I suggest taking a look at our pronunciation resource list. To get an idea of the classical pronunciation, I recommend listening to the Latin news broadcast Nuntii Latini. My understanding is that the pronunciation used there reproduces imperial Roman pronunciation quite accurately. Seeing the text and listening to the audio at the same time should quickly give you an idea of how it works. The only missing thing is macrons; vowel length is rarely indicated in writing but is needed for accurate pronunciation. A good dictionary and grammar should be able to provide you with the macrons.
Wikipedia has an extensive article on Latin pronunciation and spelling, and that will give you a number of details regarding classical pronunciation and differences to later pronunciation. Beware that Latin pronunciation is very non-uniform; people from different areas will have wildly different pronunciations, and that has been the case for centuries.
1Whenever I listen to Nuntii Latini, I notice that they seem to occasionally slip into more ecclesiastical pronunciations of certain sounds, especially "v" (using hard v instead of soft). Is this really how the imperial Romans would have spoken, or is it merely a modern regional accent so to speak?– Sam KAug 27, 2017 at 16:23
3@SamK It attempts to be close to imperial pronunciation, but of course it is affected by how Finnish is pronounced. And I believe much has been learned about classical pronunciation after the Finnish pronunciation system has been established. I lack the sufficient expertise to comment on the details such as V. The picture of Roman pronunciation given by the broadcast is certainly not perfect, but I do think it's a good start.– Joonas Ilmavirta ♦Aug 27, 2017 at 16:28
2Thank you, I listened to the podcast, and I don't know because the creators of the podcast are Finnish, but I didn't think it sounded that... high. Now that I think about it, it sounded much like modern day Italian. Thanks for the answer. Sep 7, 2017 at 21:11
