Three ways to find your voice
The script is what you want to say. The voice is how you want it to feel. Start with the option that fits your project.
Clone your own voice
Keep a familiar voice across new lines. Record yourself once with the microphone and reuse your voice in every project.

No reference in mind? Describe a new voice’s age, tone, accent, and personality, then listen and refine the direction.
Explore Voice DesignFrom written script to spoken audio
A short test makes it easier to find the right voice before you produce the full piece.
Choose a voice
Start with a ready-made voice, clone your own voice from a microphone recording, or design a voice from a description.
Write and test your script
Use natural punctuation and preview a short passage. In the workspace, adjust the delivery controls supported by your selected model.
Generate, listen, and download
Create the audio in your project, check the result, then download it or return to the project to make another version.
Your voice, with something new to say
Voice cloning remains at the heart of AltVoice. Use it when the identity of the speaker matters: a creator’s introduction, a personal story, or a recurring character.
Try a short example without signup
Record a voice sample and hear it read a fixed sentence. The demo helps you judge the result before creating an account.
Use your own script in a project
A free account lets you work with your own text, record and save your voice, and return to your generation history.
Listen for character, not just similarity
Check the pronunciation, rhythm, and tone. A cleaner recording or a different model may suit your script better.
Hear the reference. Then hear the clone.
Compare the source recording with a generated line. Listen for the voice’s character and pronunciation; the new script and delivery will not be identical to the reference.

“This is a short sample of my voice. You can use it to clone my voice and generate new speech.”

“This is the same voice, generated from text. Natural, clear, and ready to use in your projects.”
Give every scene its own sound
A voice can introduce the world. A distant engine, a forest at night, or a door opening can make it feel inhabited.
Voices for characters. Sound for their world.
Describe an original character in Voice Design, then create the ambience or effects around the dialogue. Keep related generations together in a project as you develop the idea.
An idea worth hearing.
A character, a place, a moment. Explore the prompts behind these demo concepts.
A mature, warm voice with a soft grain and a calm, unhurried pace. Intimate storytelling, gentle emphasis, natural pauses, clear English diction.
A quiet forest at night, close crickets and soft wind through pine trees, an occasional distant owl, spacious natural ambience, no music or voices.
A composed futuristic navigator with a clear, precise voice. Even pacing, a cool and reassuring tone, subtle curiosity, natural speech rather than a robotic effect.
Heavy rain on a tin roof with distant thunder. A steady textured patter, occasional larger drops, no voices or music.
Start with a real use for your audio
Write for someone who is listening. A small change in wording or delivery can make the same idea work in a different setting.
Videos and product explainers
Use a clear, conversational voice. Keep each sentence focused on one idea and leave room for the visuals.
“Here’s how it works. Choose your starting point, make it your own, and listen to the result.”
Game characters and dialogue
Give each character a consistent voice. Test a short greeting, a tense line, and a quiet moment before writing the whole scene.
“Easy, traveller. The forest has been listening, and it knows you’re here.”
Stories and narration
Choose a voice that is comfortable to hear for more than a few seconds. Use paragraph breaks and punctuation to shape the rhythm.
“By morning, the footprints were gone. Only the open gate suggested anyone had been there.”
Learning and presentations
Break unfamiliar ideas into short passages. Write out important abbreviations and check how names and numbers are spoken.
“Let’s take it one step at a time. First, listen to the example. Then try explaining it in your own words.”
A better result starts with a better script
You do not need audio engineering experience. These small checks help you spend less time regenerating.
Write the way you want it spoken
Use complete sentences and natural punctuation. For an ambiguous number or acronym, try writing the intended pronunciation in words.
Test the difficult line first
Start with names, unusual terms, or a sentence in your target language. Language coverage and delivery controls depend on the model you choose.
Change one thing at a time
Compare the same sentence with a different voice or emotion. Listen before extending the script so you can tell which change helped.
Keep the work behind the sound
AltVoice is a workspace for audio ideas, from your first test to the next version.
Projects and generation history
Keep scripts and results together. Listen to earlier takes, download completed audio, and return to the project when a line needs changing.
A library of voices to reuse
Save a useful voice for the next video or character scene. You can start with a reference today and explore a designed voice tomorrow.
More ways to work with audio
Generate sound effects from descriptions or turn a recording into text with Audio to Text. AltVoice develops its own models, operates its own infrastructure, and also works with model partners.
Meet AltVoice, from PortoText to speech and voice cloning, explained
What is AI text to speech?
Text to speech turns a written script into spoken audio. In AltVoice, you can use a ready-made voice, a clone of your own voice, or a voice created from a description.
Is AltVoice free?
A free account includes unlimited AltVoice Lite speech generation, with no credit card required. Other models can have different access and allowances; the workspace shows the options available to your account.
Do I need a microphone to make speech?
No. Choose a ready-made voice and write your script. A microphone is only needed if you want to clone your own voice.
Can I try voice cloning without signing up?
Yes. The microphone demo creates a short, fixed example in your voice without an account. Create a free account to use your own script, save your voice, and keep your work in projects.
How is Voice Design different from voice cloning?
Cloning starts with a recording and aims to preserve its voice character. Voice Design starts with a written description of a new voice, such as a calm narrator or an energetic game character. Either can become the voice for your text.
Can I change the emotion or delivery?
The workspace includes delivery controls for supported speech models. Try one direction at a time and listen to the result: the same instruction can sound different across voices and models.
Which languages can I use?
AltVoice offers multilingual speech generation. Language coverage and pronunciation vary by the selected model and voice. Start with a short passage in your target language and check names, numbers, and accents before producing the full script.
Can I download and reuse my audio?
Yes. Completed speech can be played and downloaded from your project. Keep useful voices in your library and return to saved projects to create new lines.
Can I use generated speech in videos or games?
You can use generated audio in your projects subject to our terms and commercial license. You must have the necessary rights to your script, and cloning is limited to your own voice.
Does switching models change my project?
Your script and project remain your starting point. Different models may offer different voices, languages, delivery controls, speed, and access. Review the selected model and listen to a short test before generating a longer passage.
