@Deniz Hello! Voice gender recognition can indeed be a valuable feature for personalizing interactions with a speech assistant. While VAPI itself does not provide a direct voice gender recognition feature, you can integrate third-party voice recognition services that offer gender detection capabilities. These services use acoustic analysis to estimate the gender of the speaker. Once you have the gender information, you can use it to inform your speech assistant's choice of titles. Keep in mind that gender recognition is probabilistic and may not always be accurate, especially for voices that do not conform to traditional gender characteristics. Additionally, it's important to handle this information sensitively and consider privacy and ethical implications. If you need assistance with integrating a third-party service or have any other questions, please let me know!
