Type or paste text, optionally steer the delivery with an inline instruction, and hear the result spoken aloud by a selectable voice. It is a quick way to compare voices and styles before you commit to an API integration. ## 定价与套餐 Free to use in the browser with no account required. Costs only apply if you separately call OpenAI's text-to-speech API and pay its per-character audio pricing. ## 关键功能与能力 - **Multiple voice presets:** Pick from a roster of built-in voices ranging from bright and conversational to calm and narration-friendly, then hear the same line delivered differently. - **Style instructions from plain text:** Add a short natural-language direction such as "speak slowly and warmly" to influence tone, pace, and emotion without changing the script itself. - **Instant browser playback:** Paste a paragraph or a full script and stream the synthesized audio immediately, with no signup, install, or configuration step. - **Side-by-side auditioning:** Switch voices, styles, and wording back-to-back to judge which combination fits a voiceover, audiobook, or product demo. - **Direct line to the API:** The demo mirrors the same speech generation models exposed through OpenAI's TTS endpoints, so what you hear is a good preview of what an integration will produce. - **Soundwave player:** A soundwave visualization animates while audio plays, and there is a compact embedded player for listening without leaving the page. ## 主要用例 - **Cast the right voice for a script (Voiceover creators):** Paste lines of dialogue with short style cues and audition several voices to find the right narrator for a script, audiobook sample, or podcast intro. - **Practice pronunciation with a reference read (Language learners):** Generate an English reference read of a line to hear natural pacing and intonation before you invest time in recording or hiring talent. - **Prototype before integrating the API (Developers):** Test a style prompt and a voice choice in the browser first, then replicate the same settings in code when calling OpenAI's TTS endpoint. - **Rapid copy sanity check (Product marketers):** Turn a product announcement or feature blurb into a spoken preview in seconds, so stakeholders can hear the copy rather than read it. ## 优势 - Completely free and usable without creating an account - Style prompts let you shape delivery with ordinary language instead of technical parameters - Instant side-by-side comparison across voices speeds up casting decisions - Mirrors the production models behind OpenAI's speech API, so previews are representative - No installation, plugins, or local GPU required ## 局限 - The demo is a showcase rather than a full studio — there is no project management, batch export, or voice library management - Long-form narration with fine-grained pacing and emphasis control is limited compared with dedicated TTS suites - Output is tied to OpenAI's hosted models, so there is no offline or self-hosted option - Fatigue from the looping soundwave UI affects some visitors, and access can be interrupted by bot-protection checkpoints ## 常见问题 ### Do I need an OpenAI account or API key to use OpenAI.fm? No. OpenAI.fm is a free, publicly accessible demo from OpenAI that lets visitors preview speech generation in the browser. You need your own API credentials and billing only if you want to call the TTS endpoint from an application. ### Can the voices speak languages other than English? Most gpt-4o-mini-tts voices are English-first, though several are described as multilingual and can speak other languages with varying accents. Quality in non-English languages depends on the specific voice you pick. ### What audio formats does the underlying model support? The API supports audio output formats such as MP3, Opus, AAC, and FLAC. The demo itself plays audio in the browser, so for a downloadable file in a specific format you should use the API. ### Is OpenAI.fm an official OpenAI support channel? No. It is an independent demonstration page for OpenAI's speech technology. It is not an official OpenAI support channel and it does not give access to ChatGPT or any other OpenAI product beyond speech synthesis previews. ### OpenAI.fm 的月流量和增长趋势如何？ OpenAI.fm 目前每月获得 35.9万访问量，月度环比流量变化为 +11.64万（增长率 +48%）。其主要来源市场是印度（41.5% 份额），包括每月 21.07万次直接访问和每月 — 次自然搜索访问。 ### OpenAI.fm 免费吗？它的定价模式是什么？ OpenAI.fm 采用免费定价模式。Free to use in the browser with no account required.
