⚡ Quick Verdict:
- Preisgestaltung: ElevenLabs starts at $5/month. Altered starts at $30/month.
- Ideal für: ElevenLabs for Text-zu-Sprache-Umwandlung, dubbing and voice agents. Altered for voice morphing and voice editing.
- Hauptunterschied: ElevenLabs generates new speech from written text. Altered rebuilds recordings you already have.
- Our pick: ElevenLabs for most users, based on its wider language coverage and much lower entry price.
The cheaper tool here is not the weaker one.
ElevenLabs costs $5 a month. Altered starts at $30.
But price is the least interesting difference between them.
One is an ai voice generator built around written text.
The other is an online audio editor built around voice recordings.
That single split decides which one belongs in your workflow.

| Planen | Preis | Am besten geeignet für |
|---|---|---|
| Frei | $0 | 10,000 credits monthly and up to 3 custom voices |
| Anlasser | 5 $/Monat | 30,000 credits and rapid voice clone access |

Wichtigste Vorteile von ElevenLabs
Here is what makes ElevenLabs worth a look:
- Natural sounding speech: The Eleven v3 model handles complex dialogue, accents and emotional tags. Output holds up against a natural human voice in short clips.
- KI-Stimmen: Upload samples and build a digital copy of your own voice. Generative models and neural networks do the rest.
- AI dubbing and translation: Re-voice video into more than 30 languages. Tone, emotion and timing carry across.
- Conversational AI agents: Build real-time voice and chat agents for support, sales and education. Latency stays low and Slack or Google Calendar hook in.

- Accessibility support: The ElevenReader app converts articles, PDFs and e-books into audio. It reads text aloud for on-the-go listening.
- Media and enterprise use: Studios voice audiobooks and dub films with it. Support teams automate calls with natural sounding voice agents.

Hauptvorteile von veränderten
Here is where Altered earns its place:
- Stimmverzerrung: Swap one speaker’s voice for another across characters, accents and styles. Useful for animation and voice puppeteering.
- Real-time voice changer: Ultra-low latency morphing for live calls and gaming. It works inside voice chats on most platforms.
- AI voice cleaner: Strips background noise from raw voice recordings before you edit.
- 14 Sprechstile: Emotive text to speech covers whispering, shouting and everything between. Dialogue stops sounding flat.
- Custom voice models: Train a vocal identity from your own samples. The platform also transcribes and translates into multiple languages.
- History editing: Track and revert to earlier versions of any audio project. Nothing is lost to a bad take.
- One workspace: Multiple voice AI technologies live behind a single user friendly interface.
Start with the free trial if voice editing is your main reason for looking.

- Praised by professionals in game development and podcast production

Funktionsvergleich
These two ai voice generators overlap less than the category suggests. Both use text to speech technology, but only one is built as text to speech software first. Below are ten areas where the gap actually shows.

| Startpreis | 5 $/Monat | 30 $/Monat |
| Kostenloser Plan | ✅ | ✅ |

| Am besten geeignet für | Turning written text into audio | Reshaping voice recordings |
1. Sprachqualität und Realismus
ElevenLabs: The Eleven v3 model produces realistic ai voices that hold intonation, rhythm and pacing. Deep learning techniques trained on large speech datasets drive the generative voice output. In short clips the ai generated voice sound is hard to separate from human speech.
Alter: Premium Text-to-Speech gives you natural sounding ai voices with real emotional range. Its ai generated voices avoid the flatness older computer generated voices had, though the library of speech voices is narrower. Altered leans on advanced voice AI technology rather than raw catalogue size.
2. KI-Stimmenklonierung
ElevenLabs: Voice cloning builds a digital copy of a speaker’s voice from uploaded audio files. The free tier allows up to 3 custom voices. Generative models and neural networks handle the reconstruction.
Alter: Voice cloning technology here is aimed at production teams replacing human talent on retakes. You can build a custom voice model and reuse it across a project. The cloned vocal identity stays consistent between sessions.
⚠️ Warnung: Both platforms expect consent from anyone whose voice you clone. Cloning a person without permission creates legal exposure, and the EU now fines high-risk AI misuse up to 7% of global turnover.
3. Expressive Control and Speaking Styles
ElevenLabs: Emotional tags let you fine tune delivery inside the text itself. You can push a line toward excitement, sarcasm or calm. That gives you close to complete control over how each sentence lands.
Alter: The Speaking Style system offers 14 preset options, including whispering and shouting. Voice training then adapts a model to the delivery you want. It is a cleaner route to varied voice performances than tag editing.
4. Voice Morphing and Live Voice Changing
ElevenLabs: There is a speech to speech mode, but no live voice changer. You cannot morph your voice mid-call. This is the clearest capability gap in the ElevenLabs feature set.
Alter: The real time voice changer runs at ultra-low latency for live calls and gaming. Voice morphing swaps characters, accents and styles on recorded takes too. Noise cancellation keeps the result usable in messy rooms.
5. Conversational AI and Voice Agents
ElevenLabs: Conversational AI agents handle real-time voice and chat for support, sales and education. They connect to Slack and Google Calendar. Teams also use them to power virtual assistants and IVR systems.
Alter: No agent layer exists. Altered stops at producing audio content, not conversations. If you need an artificial intelligence agent answering calls, this is not the tool.
6. Sound Effects and AI Music
ElevenLabs: Text to sound effects turns a written prompt into a usable audio file. AI Music generates studio-grade tracks the same way. That covers a full soundbed without leaving the platform.
Alter: Nothing here generates music or effects. The focus stays on the voice track alone. You will need a separate tool for score and ambience.
7. Audio Cleanup and Voice Editing
ElevenLabs: Audio enhancement tools clean up generated speech reasonably well. But they assume the audio came from the platform. Rescuing a badly recorded interview is not the design goal.
Alter: The Voice Editor works like a next generation audio editor for spoken tracks. History editing tracks every version, so voice editing stays reversible. The AI Voice Cleaner pulls background noise out before you start.
8. Languages, Dubbing and Translation
ElevenLabs: Speech synthesis covers 29 languages, and AI dubbing re-voices video into more than 30. Tone, emotion and timing survive the switch. For reaching a global audience, this is the stronger side.
Alter: Transcription and translation move content into multiple languages too. The coverage is narrower and built around existing recordings. It suits localising a finished podcast more than producing multilingual content from scratch.
9. Benutzerfreundlichkeit und Lernkurve
ElevenLabs: Paste written text, pick a voice, press generate. Voice generation time on short scripts runs to seconds. As speech software goes, this is the shortest path to high quality voice overs for a YouTube video.
Alter: Altered Studio bundles more tools, so the first hour takes longer. The payoff is one workspace instead of four. Experts credit it with making audio production simpler once you know the layout.
10. Preisgestaltung & Kosten
Here are both plan structures side by side.
| Stufe | ElevenLabs | Verändert |
|---|---|---|
| Frei | $0 | 0 €/Monat |
| Eintritt bezahlt | Starter: $5/month | Creator: $30/month |
| Mitte | Creator: $11/month | Professional: $90/month |
| Spitze | Pro: $99/month | — |
ElevenLabs: Four tiers give you room to grow slowly. At $5 a month the Starter plan is the cheapest serious entry point in this category. Credits, not seats, decide what you actually spend.
Alter: Three tiers, and the jump from free to $30 is steep. You are paying for the voice changer and editor, not just speech. For teams shipping high quality voice content every week, that maths works out.
Verschiedene Szenarien
| Falls Sie Folgendes benötigen: | Wählen | Warum |
|---|---|---|
| Knappes Budget | ElevenLabs | $5 vs $30 entry price |
| Live voice chats | Verändert | Only one with a live changer |
| Mehrsprachige Synchronisation | ElevenLabs | 29 languages, 30+ for dubbing |
| Cleaning raw recordings | Verändert | AI Voice Cleaner and editor |
| Voice agents or IVR | ElevenLabs | Built-in conversational agents |
| Beginner-friendly start | ElevenLabs | Paste text, generate speech |
💰 Ihr Budget
ElevenLabs asks $5 for its first paid tier. Altered asks $30, so the cheaper route matters if you only need ai voiceovers.

🎬 Ihr Inhaltstyp
Animated explainer videos, training videos and e learning modules start from a script, which favours ElevenLabs. Game dialogue and podcasts start from voice recordings, which favours Altered.
🎓 Dein Erfahrungslevel

🆓 Kostenlose Testversionen und Demos
Both offer a free tier, so test with your real script. Altered also runs a free trial of the Creator plan.

What Our Review Didn’t Cover
This comparison focused on solo creators and small production teams. We did not test enterprise contracts, dedicated infrastructure or API throughput at volume. Long-form audiobook runs and multi-hour dubbing jobs were outside our scope. Voice generation time was measured on short scripts only, so results on hour-long files may differ.

🏆 WINNER: ELEVENLABS
ElevenLabs wins 5 of 7 categories.
Ideal für: professional voiceovers from a script, multilingual dubbing, audiobooks, and voice agents
ElevenLabs converts text into human like voices at consistent quality. Altered reshapes voice performances that already exist. Those are two different jobs.
Altered is the better pick for game studios, voice creators and anyone doing audio storytelling from raw takes. Its voice changer has no equivalent on the other side.
Asking which is the best ai voice generator misses the point. There is no perfect voice tool for every script, only the right one for your source material.
For most people that is ElevenLabs, on price, language coverage and speed.
