This paper presents a PCI Express based system dedicated for communication with FPGA in data acquisition systems.
The system consisted of FPGA IP core containing PCIE endpoint tightly coupled with with the user core (further
denoted as “USR core”) and the DDR3 memory controller, together with Linux device driver. The Linux OS was
running on top of typical x86-64 system.
The aim of this paper was to perform acoustic analysis of normal speech signal in
order to evaluate voice quality of normal speech. Acoustic analysis included measures of
parameters such as mean fundamental frequency, Jitter local and Harmonics-to-Noise Ratio
(HNR). The parameters were extracted from speech samples representing chosen short (non-sustained)
vowels: /a/ /e/ /i/. The obtained values of parameters were compared with defined
standards of threshold pathology. Results showed that obtained values of parameters can be
used to further investigation of normal speech.
