        "content": "Here\u2019s what the *Book Port Plus* supports and uses when it comes to its Text-to-Speech (TTS) features, according to its official documentation:\n\n---\n\n## TTS Voices\n\n- The device has **two built-in synthesized speech voices**:\n  - One male voice named **Tom**\n  - One female voice named **Samantha** ([tech.aph.org](https://tech.aph.org/bt_doc.htm?utm_source=openai))  \n- You can choose between these two for reading text content that hasn\u2019t been recorded by a human narrator (i.e. non-audio files) via the System menu under *Text-to-Speech Voice*. ([tech.aph.org](https://tech.aph.org/bt_doc.htm?utm_source=openai))\n\n---\n\n## What Types of Files / TTS Is Used With\n\nThe TTS engine is utilized whenever the device is reading content that is textual (not already human-narrated audio):\n\n- Word (.doc / .docx), HTML, plain text, EPUB files count as **text** content and use the synthesized voice. ([tech.aph.org](https://tech.aph.org/bt_doc.htm?utm_source=openai))  \n- DAISY books that have *text* components will also use synthesized speech. For DAISY 3.x titles combining human-recorded audio + text, the human narration is used when present; the synthesized voice is used for text parts. ([tech.aph.org](https://tech.aph.org/bt_doc.htm?utm_source=openai))\n\n---\n\n## What It Is *Not*\n\n- It does *not* support custom TTS engines or additional voices beyond Tom and Samantha. There\u2019s no mention of external engines (like Google TTS, Microsoft voices, etc.). ([tech.aph.org](https://tech.aph.org/bt_doc.htm?utm_source=openai))  \n- The guide doesn\u2019t state that other third-party or cloud-based voices can be installed. All TTS is local and part of the firmware. ([tech.aph.org](https://tech.aph.org/bt_doc.htm?utm_source=openai))\n\n---\n\nIf you want, I can try to track down actual samples of both voices (so you can hear how they sound) or find whether users have modified/expanded the voice set."
