What Is Altered Studio?

Altered Studio is a desktop application providing AI voice generation and speech-to-speech voice transformation. Developed by Altered AI, it launched its initial public version in late 2021. The tool uses advanced AI models to convert a user's voice into a different AI voice or generate speech from text. It aims to streamline audio production workflows, offering flexibility in voice casting and post-production. The platform focuses on realistic and expressive vocal output.

Who Is Altered Studio For?

• → Podcast producers seeking to diversify voice talent or correct vocal performances.
• → Game developers needing extensive dialogue for non-player characters.
• → Film and animation studios requiring voiceovers with specific vocal characteristics.
• → Content creators looking to generate narration in various voices and languages.

⚠️ When to Avoid: Avoid Altered Studio if your primary need is real-time, ultra-low-latency voice moderation or live voice chat alteration, as its processing involves noticeable delays.

Key Features of Altered Studio

• Speech-to-Speech Voice Transformation

  We tested the speech-to-speech feature extensively. We found it could convincingly alter a recorded voice into one of its AI personas. This is particularly useful for matching a voice actor's performance to a desired character voice.

• Text-to-Speech Generation

  The text-to-speech module allows users to generate audio from written scripts. We observed a wide range of voices and emotional styles, providing flexibility for narration and character dialogue. The output quality was generally high, with natural-sounding cadences.

• Custom Voice Cloning (Enterprise)

  While not part of the standard free tier, we investigated the custom voice cloning for enterprise users. This feature enables creating a unique AI voice from a provided audio sample. It offers significant potential for brand consistency or specific character voices.

• Performance Editor

  We used the performance editor to fine-tune generated or transformed audio. It allows for adjustments to pitch, speed, and emphasis. This granular control helps achieve a more natural and expressive delivery, moving beyond basic AI synthesis.

• Multi-Language Support

  Altered Studio supports over 30 languages for text-to-speech. We tested several languages, including Spanish and German, and found the pronunciation and fluency to be quite good. This expands its utility for international content creation.
