Everything you heard above was created inside Foundry - from songs to narration to multi-voice scenes.

Speech generation in 10 languages

Open the dedicated speech language page directly from the flags below, or hit play to hear a real sample first.

Speech generation supports 10 languages. Music and lyrics support 50+ languages inside the same product.

How it works

It reads the whole thought before it ever makes a sound.

Most voice tools read words one at a time. Demodokos Foundry v4 is built on acoustic-token synthesis: a language transformer takes in the whole sentence first, modelling context, intent and delivery instead of pronouncing words in isolation. The voice is then generated from fine-grained acoustic tokens, roughly one decision every 40-80 milliseconds, which is what gives it control over timing, emphasis, rhythm, emotion and pacing down to the smallest beat.

Precomputed style embedding hybrid global style embedding
Spectral identity control speaker-similarity monitor + correction
1Text context words, intent, punctuation, instructions
2Acoustic token generation dual-track LM over discrete speech tokens
3Speaker identity conditioning speaker embedding / timbre prior
4Style / emotion conditioning prosody, pacing, affect
5Waveform decode codec / code2wav synthesis
6Final speech voice acting synthesis, natural and expressive

A full hour of finished speech in under five minutes on an RTX 5090. And all of it consistent in the correct emotions and voices.

It stays itself

Each cloned or synthetic voice is grounded in learned neural representations that capture identity, timbre, accent and vocal texture, with no hundreds of hours of fine-tuning. As it generates, identity-preserving latent conditioning and spectrogram-based consistency control keep every line locked to the same speaker.

It feels every line

On top of that identity sits an independent performance layer: more than 40 emotions and speaking styles, each in five intensity levels, on generated and cloned voices alike. Emotion, rhythm, pacing, accent and texture can change completely while the person underneath never does.

Why Foundry Changes the Game

Most cloud tools make you use separate products for music, voice, editing, and automation. Foundry brings it all together in one local studio.

First time here? Watch the 4-minute install and first-launch tutorial before you start.
1/ 5
Step 1

Pick or build a voice

Choose from built-in voice presets, clone yourself or a reference sample, or generate a brand-new voice. Cloned voices stay on your disk, they never touch a server.

2/ 5
Step 2

Paste your script

Drop in a chapter, a YouTube outline, a sales page, or a dialogue file. No character limit, no word counter watching you.

3/ 5
Step 3

Direct emotion line by line

Tag any paragraph as calm, excited, whispered, angry, sarcastic, or anything in between, with 5 intensity levels per emotion. The voice stays the same character; the feeling changes.

4/ 5
Step 4

Generate music in any style, in 50 languages

Original scores, ambient loops, full songs with vocals, instrumental beds. Any genre, any mood, sung in any of 50 languages. Drag the track straight onto your timeline. No second tool, no separate subscription.

5/ 5
Step 5

Export and publish

Render the final WAV, MP3 or FLAC locally, then drop it straight into your DAW, video editor, audiobook submission, game engine or podcast feed.

Music, Voice & Everything In Between

Generate music in 50 languages and speech in 10.

Type It. Hear It.

Describe a song, a voice-over, or a narration. Foundry generates complete audio with vocals, instruments, or spoken word, ready in seconds, entirely on your machine.

Generate music or speech from one prompt

Caption Builder

Type what you imagine: music or speech. Adjust mood, tempo, voice style, press Generate. A full track or spoken read, done in seconds.

Audiobooks & Podcasts

Turn scripts, chapters, and show segments into polished spoken audio. Multi-speaker scenes with distinct voices, emotional direction, and 15× real-time generation speed.

Turn scripts into multi-speaker narration

Script to Speech

Assign voices to roles, steer emotion per line, and produce full audiobook chapters or podcast episodes without a recording session.

Voice & Music, One Timeline

Layer narration over original scores, blend dialogue with sound design, and mix spoken word with music beds, all in the same editor. Build trailers, immersive stories, and rich audio productions without switching apps.

Layer voice, music, and effects on one timeline

Unified Timeline

Drag voice, music, and effects onto the same visual tracks. The spectrum analyzer identifies BPM, time signature, and key. Mix everything, then export your finished production.

Voices That Actually Feel

A narrator who breaks with sadness at just the right moment. A villain whose calm whisper turns to fury. A podcast host who sounds genuinely thrilled. With 40 emotions and 5 intensity levels, every cloned or preset voice stays perfectly in character.

Direct emotion line by line

Emotion Engine

Pick any emotion, from whisper and rage to heartbreak and storytelling, then dial the intensity. Assign different moods per line or paragraph. 60 speaker presets, voice cloning, and it all sounds like the same person. Not a robot.

Separate the Instruments

Take any song apart: vocals, drums, guitar, piano. Each clean on its own track. Use Karaoke mode and mix in your own vocals or an AI-generated track.

Split any song into separate instruments

Stem Separation

Splits any song into up to 7 separate tracks. Each instrument and voice gets its own channel.

Fix One Part, Keep the Rest

Something sounds off? Select just that area, generate a patch in seconds, and DSP-blend it seamlessly. Everything else stays exactly as it is.

Patch blending workflow

Patch & Blend

Select any region and regenerate just that section. Before and after stay untouched. Spectral blending ensures seamless boundaries.

Cover, Extend & Transform

Feed Foundry any audio and restyle it completely, or extend a 30-second idea into a full song. Same structure, with an entirely new character or a seamless continuation.

Cover and extend workflow

Cover & Extend Modes

Load audio as a foundation and apply a new style with Cover mode. Or select any part and press Extend to continue naturally from where it left off.

32 Studio-Grade Effects

EQ, reverb, chorus, tape warmth, voice transformation, and glitch, with 200+ presets across 7 groups. Stack freely on your timeline, non-destructive, one click.

Frequently Asked Questions

Does Demodokos Foundry work offline?

All AI generation, voice cloning, and audio processing happens locally on your GPU, nothing is uploaded to a server. However, an internet connection is required for login and license verification. The app may sign you out if it cannot reach the authentication server for an extended period. Your generated audio files and voice data never leave your machine.

What GPU do I need to run Demodokos Foundry?

Demodokos Foundry requires an NVIDIA GPU with at least 4 GB of VRAM. Any RTX series card will work well. 12 GB VRAM is recommended for best performance. GTX 1080 and newer cards are supported. AMD is experimentally supported for all Speech features, no Music.

I have an AMD GPU, will that work?

Good news! Version 2.0 includes support for AMD, though without Music generation at this point. Speech and agentic features are experimentally available.

How much does Demodokos Foundry cost?

The Creator plan is $15.00/month with unlimited AI music and voice generation. The Professional plan is $49.00/month. A free 7-day trial is included, with no charge during the trial.

Is there a free trial?

Yes. Demodokos Foundry offers a 7-day free trial with full access to all features. It is processed through PayPal with a $0 authorization, and you are not charged unless you choose to keep the subscription after the trial ends. Cancel anytime before the trial expires.

Can I clone my own voice with Demodokos Foundry?

Yes. Demodokos Foundry includes a built-in voice cloning feature. Upload a short audio sample and Foundry clones the voice locally on your machine. The cloned voice can be used with any of the 40 emotion styles and 5 intensity levels, with unlimited generation at no extra cost.

Does Demodokos Foundry upload my audio files to the cloud?

No. All processing happens on your GPU. Your audio files, voice samples, and generated content never leave your computer. There are no cloud uploads and no data sent to external servers during generation.

Is Demodokos Foundry safe for business and GDPR compliant?

Yes. Because all AI processing runs on your own hardware, your business content, client audio, proprietary voice recordings, internal scripts, and confidential narration never leaves your premises. No cloud vendor receives or retains your data. This gives your organization full data sovereignty and makes Demodokos Foundry naturally aligned with GDPR requirements without needing vendor data processing agreements for the generation itself. It is especially well-suited for companies, legal firms, healthcare, media agencies, and anyone working with sensitive or client-owned audio content.

Is Demodokos Foundry AI-Act compliant?

Yes. Demodokos Foundry is fully AI-Act compliant.

How is Demodokos Foundry different from ElevenLabs?

ElevenLabs is a cloud-based voice service that charges per character generated and requires an internet connection. Demodokos Foundry runs entirely on your own PC, has no per-generation credits or limits, and processes everything offline. It also includes full music generation, a multi-track timeline editor, and stem separation. These are features ElevenLabs does not offer.

Can I cancel my subscription anytime?

Yes. Subscriptions can be cancelled at any time, log into your account -> Billing -> Cancel. Cancellation takes effect at the end of the current billing period. No cancellation fees apply.

What languages does Demodokos Foundry support?

Demodokos Foundry supports music generation in 50 languages and speech and voice generation in 10 languages. The Creative AI music writing assistant currently operates in English.
