@vaishnav s Thanks for the details. It is not possible to identify the voice name, rate, and pitch from an already converted voice file. Once a voice file is created, the voice name, rate, and pitch information is not stored in the file.
you may be able to identify the voice name, rate, and pitch information by analyzing the recording with audio editing software. Some audio editing software can display the frequency spectrum of the audio, which can help you identify the pitch of the voice.
