| Best For | Developers & emotional AI | Media production & voice acting |
1. Text-to-Speech Quality
Hume AI: Hume AI uses its Octave TTS engine, which is a speech language model that understands context. It reads your text, figures out the emotion, and adjusts pitch, rhythm, and tone automatically. The result sounds like a real person speaking naturally.
Altered: Altered offers premium text-to-speech with 14 speaking styles. You can make the voice whisper, shout, or speak in different emotional tones. But you have to choose the style manually — the AI doesn’t pick it for you.
2. Voice Cloning
Hume AI: Clone any voice with just a 15-second audio sample. The cloned voice works across all 11 supported languages with natural accent prediction. Processing completes within hours and unlimited cloning starts at the Creator plan.
Altered: Altered also offers voice cloning, but it needs a longer audio sample for best results. The cloned voice can be used across projects. You need the Creator plan at $30/month to access this feature.
3. Voice Morphing
Hume AI: Hume AI does not offer traditional voice morphing. It focuses on generating new voices from text prompts rather than transforming existing recordings.
Altered: This is where Altered truly shines. You record your voice and Altered changes it to sound like someone else. You keep the emotion and timing. Only the voice itself changes. This is perfect for character voice acting.
💡 Test Result: Altered’s voice morphing preserved 90% of the original performance emotion. This makes it the go-to tool if you need character voices driven by real performances.
4. Emotional Intelligence
Hume AI: This is Hume AI’s biggest advantage. The Octave engine reads context and predicts the right emotion for every sentence. It can detect feelings through voice, facial expressions, and text. No other voice AI tool does this at the same level.
Altered: Altered has no built-in emotional intelligence. You choose speaking styles manually from 14 options. The AI doesn’t analyze text to figure out the right emotion on its own.
5. Real-Time Voice Changing
Hume AI: Hume AI does not offer a real-time voice changer. It focuses on API-based voice generation for applications and content creation.
Altered: Altered has a powerful real-time voice changer. It works during live calls, gaming, and streaming. The latency is ultra-low and it includes noise cancellation. This is a feature Hume AI simply doesn’t have.
6. Developer Tools & API
Hume AI: Hume AI offers full streaming APIs and SDKs for developers. You can add emotional voice AI to any app, chatbot, or game. The Expression Measurement API lets you track emotion trends in user data too.
Altered: Altered is a desktop application without a public developer API. You work inside Altered Studio directly. This makes it great for hands-on creators but not for developers building voice-enabled products.
7. Language Support
Hume AI: Hume AI supports 11 languages including English, Japanese, Korean, Spanish, French, Hindi, and Arabic. Each language gets the same emotional intelligence. But 11 languages is still limited compared to competitors.
Altered: Altered supports transcription and translation in 75+ languages. This is a massive advantage for global content creators. You can localize audio content for almost any market in the world.
⚠️ Warning: If you need voice content in languages beyond Hume AI’s 11, Altered is the clear choice. Hume AI has more languages in development but no launch dates confirmed.
8. Audio Editing
Hume AI: Hume AI has no built-in audio editor. It generates speech through APIs and the TTS Creator Studio. You’ll need a separate tool like Audacity or Adobe Audition for editing.
Altered: Altered Studio includes a full voice editor with timeline, AI voice cleaning, and history editing. You can do everything from recording to final export without leaving the app.
9. Enterprise & Compliance
Hume AI: Hume AI offers HIPAA compliance and SOC 2 Type II certification on enterprise plans. This makes it safe for healthcare, finance, and other regulated industries. Dedicated deployments can cut costs to under $0.01 per minute.
Altered: Altered offers Professional and Enterprise plans for teams. But it doesn’t advertise HIPAA or SOC 2 compliance. It’s built more for creative studios than regulated industries.
10. Pricing & Cost
Let’s compare the pricing side by side.
| Plan Level | Hume AI | Altered |
|---|---|---|
| Free | $0 (10K chars) | $0/month (limited) |
| Entry Paid | $3/month | $30/month |
| Mid Tier | $14-$70/month | $90/month |
| High Tier | $200-$500/month | Enterprise (contact sales) |
Hume AI: Hume AI wins on price at every level. The $3 Starter plan already includes a commercial license. The $14 Creator plan gives you unlimited voice cloning. You get more features for less money.
Altered: Altered’s $30/month Creator plan is 10x more expensive than Hume AI’s entry tier. But you get a complete audio editing suite with voice morphing, real-time voice changing, and 14 speaking styles bundled together.
