ARVMex: A web application for obtaining acoustic reference values for forensic studies in Spanish

“…Regarding the third formant, a decrease was also observed in the telephone attribute, and significant differences exist in both male and female speakers, with values predominantly differing by more than 1000 Hz between the two technical conditions. As [41] suggests in his study of Japanese male speakers, F3 is more impacted by channel differences. Differences attributable to technical conditions can also be visually assessed in the Graphs tab of the ARVMex tool.…”

“…Similar to [13], this study involved reading a text, but, for example, [15] utilized target words during a debriefing of the interview for their research. Another distinction lies in the fact that this study simulated a telephone call with a transformation of values to telephone bandwidth, whereas other studies, such as [41], involved mobile recordings made on a FOMA N902i (NEC) to a landline and recorded through a telephone adapter, and [13] used a standard digital telephone handset connected to another digital extension via a standard ISDN transmission line. The short-term goal with the development of ARVMex tool is to expand the data with other tasks of the CLOE corpus: semi-spontaneous speech and map task.…”
