1. 音声品質とリアリティ
イレブンラボ: The Eleven v3 model sets the bar for AI voice realism. It captures emotion, pacing, and natural speech patterns. You can add audio tags like [whispers], [laughs], and [sighs] directly in your text. Most listeners cannot tell the difference from a real human voice.
変更: Voice quality is good, especially for voice morphing output. The 14 speaking styles add emotion to generated speech. But the raw text to speech quality doesn’t match ElevenLabs in blind tests. Altered shines more when you drive the voice with your own performance.
2. Voice Cloning
イレブンラボ: Offers two types of voice cloning. Instant voice cloning needs just 30 seconds of audio. Professional voice cloning creates an almost perfect digital copy that’s nearly indistinguishable from the real voice. Both options are available on paid plans.
変更: Offers rapid voice cloning that lets you create custom voice models. The clone quality is solid but requires the Creator plan at $30/month. Altered’s cloning works best when combined with its voice morphing technology for character work.
3. Voice Morphing & Real-Time Voice Changing
イレブンラボ: Offers speech to speech conversion. You record yourself talking, then ElevenLabs transforms it into a different voice. But it doesn’t work in real time. You need to record first, then process the audio.
変更: This is where Altered truly excels. The real-time voice changer works on live calls, gaming sessions, and voice chats. The voice morphing technology changes your voice while keeping your emotion and timing. Ultra-low latency makes it feel natural.
⚠️ Warning: If you need real-time voice changing for live streams or gaming, ElevenLabs cannot do this. Altered is the clear choice for live voice morphing.
4. テキスト読み上げ
イレブンラボ: Text to speech is the core feature. Paste any text and get natural sounding audio in seconds. The v3 model handles complex dialogue, accents, and emotional tags. You can generate up to 40,000 characters in a single request.
変更: Offers premium text to speech with 14 speaking styles. You can switch between whispering, shouting, and normal speech within one project. The emotive TTS is great for dialogue and storytelling. But the voice library is smaller than ElevenLabs.
5. AI Dubbing & Translation
イレブンラボ: Automatically translates and dubs video content into 30+ languages. The dubbed audio preserves the original speaker’s tone, emotion, and timing. This is a major feature for creators who want to reach a global audience.
変更: Offers transcription and basic translation features. But it doesn’t have a full dubbing studio like ElevenLabs. You can’t automatically dub an entire video into another language with Altered.
6. Conversational AI Agents
イレブンラボ: Build intelligent, real-time voice and chat agents. These agents handle customer support, sales, and education tasks. They interact with low latency and support integrations with Slack and Google Calendar.
変更: Does not offer conversational AI agents. The platform focuses on voice editing and transformation — not building AI-powered voice assistants or チャットボット.
7. Voice Editing & Audio Cleanup
イレブンラボ: Offers basic audio tools. You can adjust speed, ピッチ, and add SSML tags. But it’s not a full audio editor. You’ll still need a separate tool for detailed editing and mixing.
変更: Includes a dedicated voice editor and AI voice cleaner. Remove background noise with one click. Edit audio timelines, track versions, and revert changes. This is a proper audio editing tool built into the platform.
8. Language Support
イレブンラボ: Supports 29+ languages with high-quality text to speech. The voice library includes 10,000+ voices across 70+ languages. This makes it ideal for creators targeting a global audience.
変更: Supports transcription and translation into multiple languages. But the voice library is smaller. Language support is good for voice morphing, but the text to speech language options are more limited.
9. AI Music & Sound Effects
イレブンラボ: Generate studio-grade AI music and custom sound effects from text prompts. This is included in your monthly credits. No need for a separate music tool like スノ or Udio.
変更: Does not offer AI music or sound effects generation. The platform focuses only on voice-related features. You’ll need a separate tool for music and sound design.
10. Pricing & Cost
Let’s compare the pricing plans side by side.
| Plan Level | イレブンラボ | 改変 |
|---|---|---|
| 無料 | $0 (10K characters) | $0/month (basic editing) |
| Entry Paid | $5/month (Starter) | $30/month (Creator) |
| Mid-Tier | $11/month (Creator) | 該当なし |
| プロ | $99/month (Pro) | $90/month (Professional) |
イレブンラボ: Far more affordable for most users. You get commercial rights starting at just $5/month. The Creator plan at $11/month unlocks professional voice cloning. At every price point, ElevenLabs delivers more features per dollar.
変更: The Creator plan at $30/month is 6x more expensive than ElevenLabs’ Starter plan. However, you get voice morphing and real-time voice changing — features ElevenLabs doesn’t offer. The value depends on whether you need those specific capabilities.
Different Scenarios
| If You Need… | Choose | Why |
|---|---|---|
| Tight budget | イレブンラボ | Starts at $5/month vs $30 |
| Realistic text to speech | イレブンラボ | Best voice realism in market |
