Comparaison des fonctionnalités
Let’s compare Altered vs Speechelo across 8 key areas.
This breakdown covers voice quality, features, and value for money.
| Fonctionnalité | Modifié | Speechelo |
|---|---|---|
| Prix initial | 0 $/mois (Forfait gratuit) | 47 $ une seule fois |
| Plan gratuit | ✅ | ❌ |
| Clonage vocal par IA | ✅ | ❌ |
| Transformation vocale | ✅ | ❌ |
| Changeur de voix en temps réel | ✅ | ❌ |
| Synthèse vocale | ✅ (14 speaking styles) | ✅ (3 tons) |
| Langues | 75+ | 23 |

| Idéal pour | Media production and voice creators | Quick voiceovers on a budget |
1. Clonage vocal par IA
Modifié : Altered Studio includes full ai voice cloning. Upload a short audio sample and the platform creates a rapid voice clone of that vocal identity. You can then use that cloned voice across any project. The voice cloning technology works for games, podcasts, and film dubbing.
Speechelo: Speechelo does not offer any voice cloning features. You can only pick from the 30+ pre-built voices. There is no way to create a custom voice or clone your own voice.
2. Morphing de la voix
Modifié : Voice morphing is the core feature of Altered. Record your own voice and change it to sound like a completely different voice. You keep the emotion and timing from your performance. Only the voice itself changes. This is voice puppeteering — you drive a different voice with your own delivery.
Speechelo: Speechelo has no voice morphing at all. It only converts text to speech. You cannot feed it your own voice recordings or transform one voice into another.
3. Qualité de la synthèse vocale
Modifié : Altered’s text to speech engine offers 14 speaking styles. These include whispering, shouting, and conversational tones. The portfolio tts voices produce high quality voice content. The voices sound more natural than basic TTS tools.
Speechelo: Speechelo offers three welsh voice tones: normal tone, joyful tone, and serious tone. The AI engine adds all the punctuation marks to make the speech sound natural. Some voices sound real and human sounding. Others can sound like a creepy robotic voice, especially female voices in certain languages.
⚠️ Avertissement: Speechelo’s standard voices sometimes produce robotic voices that are easily identified as AI. The AI engine voices are better but fewer in number.
4. Changeur de voix en temps réel
Modifié : Altered includes a real time voice changer for live use. It provides ultra-low latency morphing for voice chats on platforms like Discord or Zoom. The noise cancellation is built in. This is useful for gaming, diffusion en direct, and online meetings.
Speechelo: Speechelo does not have a real-time voice changer. It is a text-input-only tool. You type or paste text, and it generates audio. There is no live voice processing.
5. Voice Editing
Modifié : Altered Studio is a full online audio editor. It includes history editing so you can track and revert to previous versions. The voice editor handles trimming, mixing, and enhancing audio content. It is a next generation audio editor built for professional voice work.
Speechelo: Speechelo has basic voice editing. You can adjust the speed and pas of the voiceover. You can add breathing sounds and longer pauses. But there is no timeline editor or audio mixing. You edit using an online text editor, not an audio editor.
6. Assistance linguistique
Modifié : Altered supports 75+ languages with transcription and translation. You can create custom voice models in multiple languages. The extensive voice library covers accents and regional dialects for voice content creation.
Speechelo: Speechelo supports 23 languages including multiple languages like English, Spanish, French, and German. It includes female voices in Hindi, Mandarin, Polish, Dutch, Turkish, Thai, Portuguese (Brazil), and British English. The language count is much lower than Altered’s 75+.
7. Nettoyage vocal par IA
Modifié : Altered includes a built-in ai voice cleaner. It strips background noise from voice recordings automatically. This saves you from buying separate noise removal tools.
Speechelo: Speechelo does not have any voice cleaning features. Since it only generates audio from text, there is no need for noise removal. But if you record your own audio, you need a separate tool.
8. Tarification et coût
Let’s compare the cost side by side.
| Plan | Modifié | Speechelo |
|---|---|---|
| Gratuit | 0 $/mois | ❌ |
| Entrée payée | 30 $/mois (Créateur) | 47 $ une seule fois |
| Pro / Avancé | 90 $/mois (Professionnel) | Mise à niveau Pro (trimestrielle) |
| Coût annuel | $360+ (Creator) | $47 total |
Modifié : At $30/month for the Creator plan, Altered costs $360 per year. The Professional plan runs $90/month or $1,080 per year. This is a major investment. But you get voice cloning, voice morphing, TTS, and a voice editor included. For studios that currently hire expensive voiceover artists, Altered can save money long-term.
Speechelo: Speechelo costs $47 one-time for a lifetime license. No monthly fees. That makes it the cheapest option by far. But you only get basic text to speech with 30 voices. There is no voice cloning, no voice morphing, and no real-time features. The Pro upgrade adds more voices but costs $47 quarterly.
💡 Conseil de pro : If you want to create voiceovers instantly and generate human like voiceovers without hiring expensive voiceover artists, both tools can help. Altered lets you create high quality voiceovers with a professional voice feel. Speechelo helps you create human sounding voiceovers faster — though some voices sound real while others still sound like a creepy robotic voice. The right voiceover artiste alternative depends on your voice quality needs.

What Our Review Didn’t Cover
This comparison focused on individual creators and small teams. We didn’t test Altered’s Enterprise plan or evaluate its API for large-scale audio production. Speechelo’s Pro upgrade with 171 voices wasn’t part of this review either. Our observations are based on the April 2026 versions, and features may have changed since then.
