In love and sex, the voice is a decisive factor. It not only matters what is said, but also how it is said. Pitch, volume and personal expression are important to attract and retain potential partners. The same goes for sex robots and love dolls, and is true for chatbots and virtual assistants with sexual orientation as well. If you are not working with ordinary recordings, they all need artificial voices (if you decide to use voices at all). The synthetization of voices, or speech synthesis, has been an object of interest for centuries. Today, it is mostly realized with a text-to-speech system (TTS), an automaton that interprets and reads aloud. This system refers to text which is available for instance in a knowledge base or on a website. Different procedures have been established to adjust the artificial voice. This article examines how the Speech Synthesis Markup Language (SSML) can be used for sex robots and love servants. Existing tags, attributes and values are categorized in the present context and new ones are proposed to support the purpose of the special machines. In addition, a short ethical discussion takes place.
