This paper presents the research to find the appropriate Thai text set to create a special Thai speech resource for telecommunication research, called telephonometry, using a survey. This will benefit the telecommunication in Thailand. The Thai text set was designed to be in compliance with the ITU-T standard. The data gathering was from the field survey results that had been done in 7 universities for general user representatives and 6 call centers for heavy user representatives, with 702 participants. 50 highest frequently used sentences (or phrases) were investigated using keywords for each possible context and then those were analyzed. Eventually, the final result can be applied as the Thai Text Set for Telephonometry (TTST) that will also be useful to create speech samples for quality measurement of VoIP services by telecom operators in Thailand, when VoIP services are used, and voice quality is important for users and becomes an issue.
