By the end of this guide you will have recorded your own speech or singing, converted it into a different voice with AI and exported the result as an audio file. The job is done by a speech-to-speech tool: it keeps your timing and delivery and swaps the voice, which is different from typing a script into text-to-speech.
If you want to change your voice with AI, the real decision is what kind of voice you want to end up with: a stock character voice, a singing voice, or a custom voice built from permitted recordings. This guide walks through the steps and compares six tools from our Audio and voice category.
Key takeaways
- Record a clear take, choose a target voice, run the conversion, compare it with your original and export. The cleaner your recording, the better the converted result.
- The main decision is spoken or sung audio: Respeecher and ElevenLabs lean towards speech, while Kits AI and Voice-Swap are built around singing and vocal production.
- Only convert into voices you have the right to use. Cloning or imitating a real person without consent is unsafe.
- Free plans are limited: for example, Voice.ai's Free plan has no instant voice clones, and Kits AI's Free plan has no downloads.
What you need before you start
- A clear recording. Speak or sing into a decent microphone in a quiet room. Background noise carries into the converted voice.
- A script or song, ready to perform. The tool keeps your pacing, so a rehearsed read gives better results than an off-the-cuff one.
- An account with your chosen tool. Most tools here list a web app; Voice.ai also lists a desktop app.
- Permission for any voice you imitate. Use stock or licensed voices, or voices you have consent for.
- Time. Under an hour for a first converted clip.
- Difficulty. Easy for online converters, moderate for plugins and APIs.
Which kind of AI tool fits this job
Choose by the kind of audio and where you work.
An all-round audio platform. ElevenLabs lists a Voice Changer and Voice Isolator among its tools, alongside text to speech, voice cloning and dubbing. All its creative products draw from one monthly credit pool, so using the voice changer leaves fewer credits for the rest. Voice.ai combines an online voice changer with text to speech, instant voice clones and audio tools such as an audio enhancer and vocal remover.
A marketplace of licensed voices for production work. Respeecher offers speech-to-speech conversion through its Voice Marketplace of 40+ voices, including voice-actor and licensed celebrity voices. It has a Pro Tools plugin and an API, and teams use it for game characters, audiobooks, ads and podcasts.
Singing and music production tools. Kits AI has a voice converter that changes one singer into another while keeping pitch and delivery, plus a voice designer and blender. Voice-Swap has a Singing Studio for converting vocals, a roster of named voice artists, and a free VST/AU plugin for use in a DAW. It says artists are paid a royalty when their voice is used.
An API-first option. Murf AI is mainly text-to-speech, but its API includes a voice changer that converts recordings into AI voices, charged per minute.
Step 1: Decide what you want to sound like
Choose the target before you record, because it shapes the tool and the performance.
- Decide if the output is speech, singing or a character.
- Decide if you need a stock or marketplace voice, or a custom voice built from permitted recordings.
- Check the rights. Voice-Swap and Respeecher both describe licensing or rights handling, and cloning a real person's voice needs their consent.
- Write a short note of how the result will be used, such as a game, a podcast or a demo, because commercial use may need a paid plan.
Check it worked by writing one sentence that names the voice and the use.
Step 2: Record a clean source take
The converted voice is only as clear as what you give it.
- Record in a quiet room with the microphone close and steady.
- Speak or sing at a natural volume without clipping.
- Perform with the emotion and pacing you want, since conversion keeps your delivery.
- Export the take as WAV or MP3, and trim long silences at the start and end.
Check it worked by listening back on headphones for hiss, echo or popped consonants.
Step 3: Clean up the audio if it needs it
A tidy source avoids strange artefacts after conversion.
- If there is background noise, run a cleaning tool first. ElevenLabs lists a Voice Isolator, and Voice.ai lists an audio enhancer and echo remover.
- For singing, separate the vocal from the backing if you only have a mixed track. Kits AI and Voice.ai both list a vocal remover and stem splitter.
- Keep the cleaned file and the original in separate folders.
Check it worked by hearing a noticeable drop in background noise.
Step 4: Choose a tool and a target voice
Pick one tool and one voice to start with.
- Sign in and open the voice changer or converter.
- Browse the available voices. Respeecher lets you filter voices by age, gender and pitch. Kits AI has a library of royalty-free voices.
- Preview a voice if the tool allows it.
- Check the plan. Voice.ai's Free plan has no instant voice clones and 500 characters per conversion, and Kits AI's Free plan gives 15 conversion minutes with no downloads.
Check it worked by playing a preview and judging whether the voice fits the line you recorded.
Step 5: Upload your take and convert
Now run the conversion.
- Upload your recording, or record in the tool if it supports that.
- Select the target voice and any options, such as pitch adjustment. Respeecher's Pro Tools plugin lists pitch adjustment up to 12 semitones.
- Start the conversion and wait for it to finish.
- Keep the first result as a draft.
Check it worked by playing the converted file from start to finish.
Step 6: Compare and refine
Judge the result against the original, then fix what is wrong.
- Listen for words that are slurred, clipped or oddly pronounced.
- Check the timing and emotion. If the delivery flattened out, re-record with more expression.
- Try a second voice, or a different setting, and compare.
- For longer projects, fix problem lines individually instead of redoing the whole file.
Check it worked by choosing a version you would be comfortable publishing.
Step 7: Export and label it
Save the final file in the format you need and be honest about how it was made.
- Export the converted audio. Voice.ai lists text to speech file downloads and the commercial licence starting at Starter, so check the plan before you publish.
- Keep the original recording and the settings you used.
- If the voice resembles a real person or is clearly synthetic, say so where the audio is published.
- Check any platform rules for AI-generated voices before uploading.
Check it worked by playing the exported file in the app where it will be used.

Common mistakes to avoid
- Imitating a real person without permission. A convincing copy of someone's voice can mislead listeners and may break the law or platform rules. Fix it by using licensed or stock voices, or by getting written consent.
- Starting from a noisy recording. Noise and echo carry into the converted voice and sound worse after processing. Fix it by recording in a quiet room and cleaning the take first.
- Under-performing the source. Conversion keeps your delivery, so a flat read gives a flat result. Fix it by acting out the line as you want it to sound.
- Ignoring licence terms. Free plans may not allow downloads or commercial use. Fix it by checking the plan before you publish, for example that Voice.ai's commercial licence starts at Starter.
- Spending a shared credit pool on experiments. On ElevenLabs, all creative products share one credit pool. Fix it by testing with short clips before converting a long file.

Frequently asked questions
Can I change my voice with AI for free?
Within limits. ElevenLabs has a Free plan with 10,000 credits a month, Voice.ai has a Free tier with 5k credits a month, Kits AI's Free plan gives 15 conversion minutes with no downloads, and Respeecher offers a free trial. Check what each free plan lets you export.
Is it legal to use an AI voice changer?
Using a changer on your own voice or a licensed voice is generally fine, but rules vary by country and platform. Imitating a real person without consent can cause legal and ethical problems. If the voice will be published, check the licence terms and any platform rules, and take legal advice for commercial projects.
Can I use a voice changer on a phone?
The tools covered here are mostly web based, and Voice.ai also lists a desktop app. The listings do not describe phone apps for the voice changers, so check the vendor's site for mobile support.
Is it speech-to-speech or text-to-speech?
Voice changing is speech-to-speech: you perform the line and the tool swaps the voice. Text-to-speech starts from typed text. Respeecher, ElevenLabs, Voice.ai and Murf AI list both.
Can I use the converted voice commercially?
It depends on the plan and the voice. Voice.ai's commercial licence starts at Starter, and Respeecher licenses its marketplace voices. Read the licence for the exact plan before you publish or sell anything.
