A semiconductor processing system including a semiconductor processing apparatus and a gas supply apparatus for supplying a process gas into the semiconductor processing apparatus includes a control section configured to control an operation of a pressure adjusting mechanism for adjusting the pressure inside a vaporizing chamber. The control section is preset to cause the pressure inside the vaporizing chamber to fall within a predetermined pressure range with reference to a pressure detection value obtained by a pressure detector. The predetermined pressure range is defined by an upper limit lower than a first limit value, at which vaporization of the liquid material starts being inhibited due to an increase in the pressure, and a lower limit higher than a second limit value, at which vaporization of the liquid material starts being unstable and the pressure inside the vaporizing chamber starts pulsating movement due to a decrease in the pressure.

An apparatus comprises microphone receivers (101) which receive microphone signals from a plurality of microphones (103). A comparator (105) determines a speech similarity indication indicative of a similarity between the microphone signal and non-reverberant speech for each microphone signal. The determination is in response to a comparison of a property derived from the microphone signal to a reference property for non-reverberant speech. In some embodiments, the comparator (105) determines the similarity indication by comparing to reference properties for speech samples of a set of non-reverberant speech samples. A generator (107) generates a speech signal by combining the microphone signals in response to the similarity indications. In many embodiments, the apparatus may be distributed over a plurality of devices each containing a microphone, and the approach may determine the most suited microphone for generating the speech signal.
