I'm sharing this here mostly due to the alphabet. The relevant region (Tartessos) would be roughly what's today the western parts of Andalucia, plus the Algarve.

Here are the news in Spanish, for anyone interested.

The number of letters is specially relevant for me - 32 letters. The writing system is a redundant alphabet, where you use different graphemes for the stops, depending on the next vowel; and it was likely made for a language with five vowels, so you had five letters for /p/, five for /t/, five for /k/. Counting the "bare" vowels this yields 20 letters; /m n s r l/ fit well with that phonology, but what about the other seven?

Thank you to linguist Gretchen McCulloch for teaching me about phonetic assimilation, and for teaching me that if you stand around in public reading texts from a linguist and murmuring example phrases to yourself, people will eventually ask if you're okay.

they were taking part in an unusual experiment, which involved tracking their own voices over time. This was done by making 10-minute recordings every few weeks. They would sit in front of a microphone and repeat the same 29 words as they appeared on a computer screen. Food. Coffee. Hid. Airflow.

One of those changes was the "ou" sound in words such as "flow" and "sew" that shifted towards the front of the vocal tract.

I'm not actually sure what sound change they're describing there. Can anyone explain with examples or IPA?

edit: Cheers for the answers (turns out I misunderstood which part is the vocal tract)

This is not bad
