Dia TTS AI Voice Cloning — Generate Speech from a Reference Voice
Dia TTS AI Voice Cloning generates speech that resembles the voice in a reference audio sample. Upload your own voice or a voice you have explicit permission to use and clone, then enter the text you want the generated voice to speak. The current page accepts one reference audio file per generation. You can also provide an optional transcript of the reference recording. When the audio is ready, you can preview it in your browser and download the generated file. New users can sign up and use complimentary credits to try the service. Results are affected by factors such as the clarity of the reference audio, the recording environment, speaking style, language, and target text. Voice similarity may vary, and an exact replication of the original voice is not guaranteed.

Input
What you choose to call me is of little importance. Through the ages, I have watched in silence as life evolved, civilizations flourished, and empires crumbled into dust. Never forget that I am ancient, powerful, and enduring. Treat me with respect, and I will sustain and protect you. Neglect or defy me, and sooner or later, you will suffer the consequences.

Why Use the Dia TTS AI Voice Cloning
Upload a clear reference recording, and Dia TTS will analyze its vocal characteristics and generate speech that resembles the reference voice using your target text. It is intended for creating new audio with your own voice or a voice you have explicit permission to use for voice cloning.
The page requires three main inputs: a reference audio file, an optional reference transcript, and the text you want the generated voice to speak. There is no complicated configuration. Once your audio and text are ready, you can submit the generation request.
Reference audio can be uploaded in MP3, OGG, WAV, M4A, or AAC format. Files can be up to 10MB and must not exceed 30 seconds. Each generation accepts up to 5,000 characters of target text, making it suitable for narration, podcast segments, lesson content, and product explanations.
There is no software to download or install. New users can sign up and use complimentary credits to try AI voice cloning. When the generation is complete, you can preview and download the result directly from your browser. Estimated credit usage is calculated according to the length of the target text.
How to Use Dia TTS AI Voice Cloning
Upload an Authorized Reference Sample
Upload a recording of your own voice or a voice you have explicit permission to use and clone. The reference audio should contain clear, continuous speech from one main speaker.
- •Use only your own voice or a voice you have explicit permission to use and clone
- •Choose a clear recording with one main speaker
- •Avoid background music, environmental noise, and noticeable echo
- •Use natural speech with a reasonably consistent volume
- •Upload an MP3, OGG, WAV, M4A, or AAC file
- •Keep the file under 10MB and the audio no longer than 30 seconds
Add the Reference Transcript and Target Text
If you know what is being said in the reference audio, you can enter the matching words in the reference transcript field. The transcript is optional, but when provided, it should match the actual spoken content as closely as possible. Next, enter the text you want the generated voice to speak. Each generation supports up to 5,000 characters. Punctuation, sentence length, and wording may also affect pauses and speaking rhythm.
Generate, Preview, and Download
Review the reference audio, reference transcript, and target text, then submit the generation request. When the audio is ready, you can preview it directly in your browser and download the generated file. If the result does not meet your expectations, try using a clearer reference recording, correcting the reference transcript, adjusting the punctuation, or revising the target text before generating again.
Who Uses Dia TTS AI Voice Cloning
AI voice cloning is suitable for creators, education teams, and businesses that need to create new content using their own voice or another voice they have permission to use and clone.
Personal Narration and Content Creation
Use a sample of your own voice to create new narration for videos, articles, and social media content. When recording again is inconvenient, you can use an existing clear voice sample to produce new spoken content.
Podcasts and Spoken Content
Generate audio for podcast segments, spoken articles, show introductions, and content drafts. Using the same authorized reference recording can help different segments retain similar vocal characteristics.
Training and Product Explanations
Use the authorized voice of an instructor, employee, or brand representative to create audio for training materials, product explanations, and internal instructions. When the written content changes, you can enter the updated text and generate a new version without recording the entire script again.
Character and Creative Prototypes
Create draft character voices for stories, games, animation, and other creative projects. Before the final recording, you can test dialogue using your own voice or a performer’s voice that you have explicit permission to use and clone.
