Words and audio stay on this page.
The online studio uses the deployment key with a fair-use limit. External APIs use a NorSpeak key from your account and spend quota. A pasted upstream key is still forwarded as-is.
Why free aivoice here
NorSpeak is a free aivoice workbench in the browser: text-to-speech, live duplex calls, captions, and speech-to-text on one page. Paste a line to hear it, or open the studio to talk. When you need more quota, the same routes are the paid API.
For creators, support teams, and developers. Live calls, transcription, and read-aloud stay on this page.
NorSpeak keeps listening, speaking, and transcribing on a single page, so you can judge the sound before you commit to an integration. Open the site, paste a sentence, and hear it through the same read-aloud route the studio uses. If the line feels flat, switch the voice or the language and play it again. The browser tab is the product. There is no desktop installer and no separate editor to learn.
A live call is the next step on this same address. You speak, captions land beside the audio, and the transcript stays in the tab until you export text, subtitles, or JSON. Creators use that path for a product walkthrough, a short interview, or a lesson voiceover. Support teams use it to hear how a reply will sound before a customer does.
Speech-to-text sits next to playback. Upload a recording or dictate in the workbench, then send the words back through the reader when you want a second pass. Chinese, English, and Japanese share one key. When a demo needs more quota, the same three routes—read aloud, transcribe, and realtime—are the ones your own worker calls. This page is where you learn their shape. The key stays in a worker secret or in this browser, and the public site only forwards the request.

一次会话怎么在这一页走完
A useful session stays on this address. You do not create an account here, and you do not download a recorder. The first check is whether a sentence sounds right. The orb in the capability panel plays a fixed Chinese line through the read-aloud route. The reader card lower on the page takes your own text, a language, and one of six voices, then returns an MP3 the same way.
When the line is right, open the studio. The hash changes to studio and the document stays on the homepage. Allow the microphone. The default call is full duplex on the flagship voice model. If the room is noisy, switch to hold-to-talk so the microphone is only open while you press. Captions land beside the call. A file transcription uses the same record as the live captions, so you are not copying between tools.
Export stays in the browser: plain text, SRT subtitles, and JSON. A short summary can be taken from the transcript and sent back through the reader if you want to hear the recap. The audio request, the file upload, and the live socket all go to this site first. The worker forwards them. The browser never puts the server key on the upstream URL. A pasted key stays in session storage unless you choose to remember it on this computer. Leave that box unchecked on a public machine. An optional access token only unlocks a worker-held key for the current tab. It is not the voice key.
Six built-in voices cover the reader. Ara is warm and friendly, Eve is a bright British voice, Leo is steadier, Rex is clear and confident, Sal is smooth and even, and Luna is patient and soft. Language is separate: Chinese, English, Japanese, or automatic. Automatic helps when a paragraph mixes languages. A lesson that must stay in one language should set the code so the reading does not drift.
The model stack lists the realtime names. The latest alias always points at the current flagship. The older 2.0 name is kept so existing clients still resolve. File transcription has its own default model. The read-aloud route does not take a model name. It needs text and a language, and a single request stops at 8000 characters, so split a long script. Try the call in the studio, then repeat that shape from your own worker. The page and the API are one chain.
这一页把试听、通话和转写放在一起，适合先确认声音，再决定要不要接到自己的程序里。
先听。能力区中间的圆钮会播放一句固定的中文。再往下，朗读卡片可以贴上你自己的文字，选择中文、英文、日文或自动，并换成六种音色之一。单次朗读有长度上限，更长的稿子分成几段即可。
再通话。打开工作台后地址仍然是首页。允许麦克风之后，默认是全双工。环境吵的时候可以改成按住说话。字幕和文件转写写在同一条记录里，结束后可以导出纯文本、字幕或 JSON。摘要在浏览器里抽出，再交给朗读听一遍。
最后看接口和密钥。浏览器只请求本站，再由转发层送到上游。服务器上的密钥不要写进仓库。粘贴到页面的密钥默认只留在这次会话，公共电脑不要勾选记住。访问令牌只用来放开服务器上的额度，并不是语音接口的密钥。
创作者、客服和做集成的人可以按这个顺序使用：浏览器里就能把 free aivoice 走完，先听一句，再留下一场对话，确认无误后再接 API。
Who uses this page
Three kinds of work fit on this page, and they can happen in one sitting.
A creator usually starts with a sentence that has to sound like the product. Paste the line into the reader, pick a language, and step through the voices until the tone is right. Ara stays warm, Rex stays direct, and the others sit between them. The playback you hear is the read-aloud route, so a later API call does not surprise you with a different engine.
A support lead or interviewer needs the words, not only the sound. The studio keeps the call and the captions in one record. Full duplex is the default. Hold-to-talk is the fallback when a room is loud. Export text, subtitles, or JSON when the conversation is finished, and read a short summary back if you want to check the recap by ear.
Someone wiring the API can watch those same steps and then read the resource section. The read-aloud call is JSON. Transcription is a file upload. The live socket begins with a hello frame and does not put the key in the address. Once the studio behaves the way the integration should, the worker in front of this page is the client to copy.

Free online, paid API
NorSpeak API keys are stored as hashes. The secret is shown once, when you create it.
Browser calls without a key must be same-origin and stay inside a fair-use limit.
Paid keys check plan quota. TTS is per character, STT per transcript character, realtime per minute.
常见问题
What is free aivoice?
It is the browser workbench on this site: text-to-speech, speech-to-text, and a live duplex call with captions, kept on one page. There is no desktop app to install. Paste a line to hear a sample, or open the studio when you want the conversation written down beside the audio. Chinese, English, and Japanese can share that session. When you need more quota, the same routes are available from your own worker.
Is NorSpeak free AI voice?
Yes. Open this page and try the workbench in the browser: paste a line, play it, and start a live call with captions. A NorSpeak API key authorizes the voices. Keep that key in this browser, or in a worker secret if you deploy the page yourself. It does not belong in the repository. When a project needs more quota, call the same read-aloud, transcribe, and realtime routes.
How to start free aivoice online?
Start on this page. Play the sample in the capability panel, or scroll to the reader and paste your own line. Choose a language and a voice, then listen. To talk instead of type, open the studio, allow the microphone, and speak. Captions stay next to the call. Export the transcript when you are done, or read a short summary back. The resource section shows the same three routes if you later call them from your own app.
