AI Audio and Music Tools
The best AI audio tools split into three jobs: making music, making speech, and understanding speech. Suno AI and Udio write full tracks from a text prompt. ElevenLabs, Murf AI and Play.ht turn a script into a voiceover. AssemblyAI, Deepgram and Voxtral transcribe and analyze recordings, and Krisp cleans up noisy ones before anything else touches them. Pick by job first, then by whether you need a hosted app or an API you can call from code. All nine tools here are freemium, so you can test before you pay.

Audio & Music tools
What kinds of AI audio tools are there?
Four jobs, and most tools only do one of them well. Music generation: Suno AI and Udio produce finished tracks with vocals, instruments and lyrics from a text description, which is what you want for a demo reel or a placeholder game soundtrack. Voice generation: ElevenLabs does realistic voice cloning, Murf AI ships more than 200 studio voices aimed at e-learning and presentations, and Play.ht covers 900+ voices across 142 languages. Speech recognition: AssemblyAI layers speaker diarization and sentiment analysis on top of transcription, Deepgram targets fast real-time transcription, and Voxtral from Mistral handles audio up to 40 minutes with built-in Q&A and summarization. Cleanup: Krisp strips background noise and echo from a call while it is happening.
How do I choose between them?
Start with the shape of the integration. Deepgram, AssemblyAI, Play.ht and Voxtral are APIs you call from code. ElevenLabs, Murf AI, Suno AI and Udio are usable straight from an interface with nothing written. If you are shipping a product feature rather than a one-off asset, the API surface matters more than the demo quality. Then check licensing. Voxtral is released under Apache 2.0, so you can self-host the models instead of renting them, which is a different risk profile from a hosted-only vendor. For generated music, read the commercial-use terms before you build a catalog on top of it. Every tool in this category is freemium, so the cheapest way to decide is to run the same 30 seconds of your real audio through two or three of them and compare.
Frequently asked questions
- What is the difference between a voice generator and a speech-to-text tool?
- A voice generator goes from text to audio. ElevenLabs, Murf AI and Play.ht read a script aloud in a synthetic voice. Speech-to-text goes the other way, turning a recording into a transcript. AssemblyAI, Deepgram and Voxtral do that, and add extras like speaker labels, sentiment analysis or summaries on top of the raw text.
- Can I generate a complete song with AI?
- Yes. Suno AI generates full songs with vocals, instruments and lyrics from a single text prompt in seconds, and Udio creates studio-quality tracks in any genre from a text description. Both are freemium. Before you use a generated track commercially, check the terms of the specific plan you are on, because rights vary by tier and by tool.
- How many AI audio tools are listed in this category?
- Nine, and all nine are freemium: ElevenLabs, AssemblyAI, Deepgram, Krisp, Murf AI, Play.ht, Suno AI, Udio and Voxtral. They cover music generation, voice synthesis, transcription and noise removal. Video generation tools live in the separate Video and Audio category, so this page stays on music, voice and sound.
