Flat text-to-speech has been around for years. You paste text, you get audio, and it sounds like a GPS giving directions. Technically correct, emotionally dead. Foundry takes a different approach.
The delivery style system
Every voice in Foundry, whether it is a built-in preset or a cloned voice, supports 38 delivery styles with 5 intensity levels. The styles cover emotion, drama, narration, and character states. That includes familiar emotions such as happy, sad, and angry, dramatic direction such as heroic or villainous, narration such as storytelling or documentary, and states such as exhausted, breathless, whispering, drunken, or singing.
You can assign different delivery styles to different parts of your script. The narrator starts calm and measured. By the climax, the voice carries tension. In the resolution, it softens. This is not post-processing or pitch tricks. The generation model produces the performance directly in the audio.
Some examples of what this enables:
- An audiobook narrator who genuinely sounds heartbroken during a character's loss
- A podcast host whose excitement sounds real, not performed
- A game villain whose cold calm shifts to rage at exactly the right moment
- A children's story narrator who sounds warm and playful throughout
Voice cloning
The 60 built-in speaker presets cover a lot of ground. Male, female, young, old, deep, bright, gravelly, smooth. But sometimes you need a specific voice.
Voice cloning creates a new voice profile from a short audio sample. Record yourself, or use an existing recording. Foundry captures the vocal characteristics and builds a reusable voice that works with the full delivery style engine.
The cloned voice stays consistent. If you generate a 30-minute audiobook chapter with a cloned voice, it sounds like the same person from start to finish. Different delivery styles, different energy levels, but always recognizably the same voice.
Direction inside the rich document
Scripts rarely have one mood throughout. A conversation shifts. A story builds. An advertisement has energy peaks and quiet moments.
Foundry lets you direct a short sentence or an entire chapter inside one rich document. Delivery styles can change wherever the performance calls for it. Multiple speakers can overlap, interrupt each other, and use natural crosstalk. Music, effects, and custom delays sit in the same document, and the exact arrangement is shared by preview and export.
All of this runs locally
Voice cloning samples stay on your computer. The emotion model runs on your GPU. Nothing is uploaded to any server. For anyone working with client voices, sensitive scripts, or unreleased material, this matters. Your voice data never leaves your machine.
