The status of a woman from the level of menstrual cycle to the various stages of pregnancy can be studied using various phonetic parameters. Simultaneous use of behavioural characteristic of amplitude,frequency,time duration,energy can pinpoint the status of a pregnant woman as well as the status of foetus including the delivery time and regarding the original condition , i.e. non-pregnant level. The proposed phonetic technique is comparable with other medical technique like pathological testing / C T Scan / X-ray etc.The conventional medical techniques are costlier as well as inconvenient to use and may have adverse effect on growth of foetus.
