The present subject matter describes a system and method for estimating properties and physiological conditions of organs by analysing speech samples of the said user. The user device records the specifics of speech and uses these as a speech sample of the user's utterance. The user device transmits the speech samples and the metadata to the processor. The processor isolates phonation segments from the speech samples. The processor filters phonation segments. The processor isolates uttered speech segments from phonation segments. The processor performs acoustic-phonetic analysis of the uttered speech segments in order to determine speech markers and the corresponding dimensions of the organ(s). The International Phonetic alphabets (IPA) phonemes are used to derive speech markers that corresponds to specific organs and their dimensions. The system may generate a report based on organ dimensions, wherein the report is transmitted to the user.
