1. AI音声クローン
変更: Altered’s voice cloning technology creates a rapid voice clone from a short audio sample. The cloned voice works across multiple languages, supporting cross-lingual cloning. This helps voice creators maintain a consistent vocal identity across different projects and regions.
ダップダブ: DupDub’s voice cloning lets you create a digital clone of a specific voice from a short sample. It supports basic cross-lingual use, but the depth of control is more limited than Altered’s approach. DupDub positions this as a tool for brand consistency in marketing and training content.
2. 音声モーフィング
変更: Voice morphing is Altered’s standout feature. You can modify any voice recording into different characters, accents, and styles. This is useful for game developers who need multiple voice performances from a single recording session and for podcasters creating varied audio content.
ダップダブ: DupDub does not offer voice morphing. If you need to transform a recorded voice into a different character or style, DupDub cannot do this. You would need to pick from its extensive voice library of different voices instead.
⚠️ 警告： Voice morphing is only available in Altered. If transforming existing voice recordings is part of your workflow, DupDub is not the right choice for that specific task.
3. テキスト読み上げ
変更: Altered’s premium text to speech offers 14 speaking styles including whispering and shouting. The emotive text to speech engine provides flexible voicing for dialogue, making it a strong fit for audio storytelling and professional voice performances. It also supports portfolio TTS voices.
ダップダブ: DupDub’s text to speech feature transforms written scripts into natural sounding voiceovers in seconds. It offers over 500 natural voices across 70+ languages, giving you a wider selection. However, DupDub lacks the emotive speaking style controls that Altered provides.
4. AIアバターの作成
変更: Altered does not offer AI avatar creation. The platform is focused entirely on voice and audio editing. If you need talking avatars or digital presenters, you’ll need a separate tool.
ダップダブ: DupDub’s AI avatar feature lets you create ai avatars that speak and express emotions. You can customize avatars with different hairstyles, outfits, and accessories. This makes DupDub a valuable tool for creating engaging content like marketing pitches, training videos, and YouTube faceless channels.
5. ビデオ編集
変更: Altered is an audio-only editor. It does not include video editing tools, background music options, or screen recordings. If you need to produce finished videos, you’ll need a separate video editing platform alongside Altered. However, its transcription capabilities let you convert voice recordings into text.
ダップダブ: DupDub includes video editing tools that let you add subtitles, background music, and sound effects to your projects. You can start producing high quality videos directly inside the platform, making it an all in one platform for content creation.
6. Real-Time Voice Changer
変更: Altered’s real time voice changer works during live voice chats on diverse communication platforms. It provides realistic voice alterations with effective noise cancellation. The ultra-low latency makes it suitable for gaming and professional calls.
ダップダブ: DupDub does not offer a real-time voice changer. Its voice features work only with pre-recorded or generated audio files. For live voice changing during calls or gaming, Altered is the only option here.
7. 動画翻訳＆吹き替え
変更: Altered supports transcription and translation of content into multiple languages. However, it does not include video dubbing with lip sync. The focus is on voice and text translation rather than full video localization.
ダップダブ: DupDub supports video translation and dubbing into over 130 languages. The platform maintains audio quality and lip movement synchronization. 仕事 teams use DupDub to localize marketing campaigns quickly by dubbing an english video into multiple target languages.
8. AI Voice Cleaner
変更: Altered Studio includes a built-in AI voice cleaner that strips away background noise from voice recordings. This removes the need for professional studio conditions. The cleaner preserves vocal clarity while removing hums, echoes, and ambient sound.
ダップダブ: DupDub offers basic audio customization but does not have a dedicated AI voice cleaner. If your source audio files have background noise, you’ll need a separate tool to clean them before importing into DupDub.
9. 価格設定とコスト
料金プランを並べて比較してみましょう。
| プラン | ダップダブ | 改変 |
|---|---|---|
| 無料 | 月額0ドル | 月額0ドル |
| 入場料支払い済み | 月額11ドル（個人向け） | 月額30ドル（クリエイター向け） |
| 中級 | 月額30ドル（プロフェッショナルプラン） | 月額90ドル（プロフェッショナルプラン） |
| トップティア | 月額110ドル（アルティメットプラン） | カスタム（エンタープライズ） |
変更: Altered’s entry price is $30/month for the Creator plan. The Professional plan jumps to $90/month. This pricing reflects the specialized tools for producing high quality voice content. For voice creators who need advanced voice morphing and a professional voice editor, the cost is justified.
ダップダブ: DupDub starts at just $11/month, making it the more affordable option. Even the Professional plan at $30/month matches Altered’s entry price while offering video editing and avatar tools. DupDub is the clear budget pick for creators who need a user friendly interface at a lower cost.

What Our Review Didn’t Cover
This comparison focused on solo creators and small teams. We didn’t test enterprise-level features, API integration, or high-volume production workflows. Our observations are based on the May 2026 versions — features may have changed since then. If you’re managing a large production studio with dozens of voice artists, your priorities may differ from what we’ve covered here.

最適な用途: Voice creators, ポッドキャスト producers, game developers, and audio storytelling professionals
Altered and DupDub serve two different types of creators. Altered gives you deep control over voice — morphing, cloning, cleaning, and real-time changing. DupDub gives you everything else — avatars, video editing, and affordable voiceover generation.
DupDub is excellent for video-first creators who need human like voiceovers and talking avatars on a budget. However, if your work centers on voice quality, character performances, or professional audio production, Altered is the better choice.
