A speech sample of Microsoft Sam, using the SAPI 5 version of the voice. The first part uses a variation of "The quick brown fox jumps over the lazy dog" panagram. The second part demonstrates the "soy/soi" glitch associated with Sam. Microsoft Sam is the default text-to-speech male voice in Microsoft Windows 2000 and Windows XP.
Synthesized voices typically sounded male until 1990, when Ann Syrdal, at AT&T Bell Laboratories, created a female voice. [27] Kurzweil predicted in 2005 that as the cost-performance ratio caused speech synthesizers to become cheaper and more accessible, more people would benefit from the use of text-to-speech programs.

Adult men and women typically have different sizes of vocal fold; reflecting the male–female differences in larynx size. Adult male voices are usually lower-pitched and have larger folds. The male vocal folds (which would be measured vertically in the opposite diagram), are between 17 mm and 25 mm in length. [10] The female vocal folds are ...
The voiced speech of a typical adult male will have a fundamental frequency from 90 to 155 Hz, and that of a typical adult female from 165 to 255 Hz. [3] Thus, the fundamental frequency of most speech falls below the bottom of the voice frequency band as defined.
Whisper is a machine learning model for speech recognition and transcription, created by OpenAI and first released as open-source software in September 2022. [2]It is capable of transcribing speech in English and several other languages, and is also capable of translating several non-English languages into English. [1]
Each speaker recognition system has two phases: enrollment and verification. During enrollment, the speaker's voice is recorded and typically a number of features are extracted to form a voice print, template, or model. In the verification phase, a speech sample or "utterance" is compared against a previously created voice print.
