Q: What are the requirements for SID evaluation dataset?

For evaluating the real life scenario of Phonexia Speaker Identification technology, the system needs to be calibrated by SID dataset. SID dataset (minimum requirements): To measure SID performance precisely, it’s important to prepare evaluation recordings set very carefully. The requirements are: 50+ known speakers, 200+ recordings in total (i.e. 3 to 5 recordings per speaker*) 1+ minute of net speech…

Speaker Identification (SID)

…this Microsoft Excel sheet demonstrating the sigmoid function: Score-to-Confidence. SID evaluation Before implementing Speaker Identification, it’s important to evaluate its accuracy using real data from the production environment. To evaluate the SID system, you’ll need enough of labeled data, i.e. recordings with speaker labels. The principle of SID system evaluation is to compare (voiceprints of) all the individual recordings against…
