The word "Tartro" is an unusual spelling, but it can be explained using IPA phonetic transcription. The first sound is a voiceless dental fricative "θ". This is followed by an unstressed "ɑ" vowel and a retroflex approximant "ɻ" sound. The final sound is an open-mid back unrounded vowel "ɔ". The spelling of "Tartro" may be confusing, but with the help of IPA transcription, its pronunciation can be deciphered.
