ChatGPT Realtime Audio
- Realtime-2 — voice agent · GPT-5-class reasoning · $32 / $64 per 1M audio tokens
- Realtime-Translate — live translation · 70 → 13 languages · $0.034 / min ≈ $2.04 / hour
- Realtime-Whisper — streaming speech-to-text · $0.017 / min ≈ $1.02 / hour
This page is the honest comparison vs Whipscribe — last price-check 2026-05-08.
If you're a developer building a voice agent and you want GPT-5 reasoning on the audio path with a single endpoint — Realtime-2 is the right tool, and Whipscribe doesn't compete on that.
If you want a transcript — paste a URL, drop a file, or hit an MCP/REST endpoint — your first Whipscribe transcript in the web app is free, at any length (API keys draw on account credit). After that, credit packs start at $8 for 1,000 minutes ($0.008/min, already under Realtime-Whisper's $0.017/min), and bigger packs bring the rate down: $12 buys 2,000 minutes (effective $0.36/hr, about a third of ChatGPT Realtime's ~$1.02/hr). Every pack is one-time payment, credits never expire, no subscription. Preview any transcript instantly with no signup. 99 languages, speaker labels included, no audio sent to OpenAI servers.
If you care about privacy — Whipscribe runs self-hosted faster-whisper / whisperX with no third-party AI calls on the audio path; ChatGPT Realtime sends every audio stream to OpenAI's US servers, retained per OpenAI's data-usage policy.
The three new models
GPT-Realtime-2
Voice agent with GPT-5-class reasoning. Carries multi-turn dialogue, calls tools, executes actions while the user is still talking. The flagship — and the most expensive of the three.
GPT-Realtime-Translate
Live speech-to-speech translation. 70 input languages → 13 output languages, low-latency streaming. Aimed at meeting bots, dubbing, and customer-support overlay use cases.
GPT-Realtime-Whisper
Streaming speech-to-text. Same Whisper family OpenAI has shipped before, now exposed as a real-time stream so partial transcripts appear as the speaker talks. The closest direct competitor to Whipscribe's transcription API.
Pricing pulled from OpenAI's launch announcement on 2026-05-08. Audio billing is rounded to the nearest second; Realtime-2 token math depends on input length.

What Whipscribe ships that ChatGPT Realtime doesn’t
Realtime is a developer audio API — its job ends at "stream out the bytes." Whipscribe ships the finished workflow: the transcript file, the place to keep it, the AI to talk to it, and a human you can email when something is off. Four pieces, all included on every paid pack, none of them on the Realtime side without you building them yourself.
📁 Files of any size, any format
Drop a 3-hour podcast .mp3, a Zoom .mp4, an iPhone Voice-Memo .m4a, a .wav, a .mov, an .opus — Whipscribe decodes it. Up to 10 hours / 5 GB per file (3 hours before you buy credits), and you can drag a whole folder in for parallel jobs. No chunking code, no resampler, no "audio format not supported." Realtime accepts a raw audio stream — file ingestion is on you.
🔍 A searchable library that’s yours
Every transcript you make is saved to your account, full-text searchable across the whole library — find "the meeting where we discussed pricing" in one query, six months later. Folders, share links, trash with restore, rename, re-export anytime. Realtime returns token deltas; archive + search + share is something you build.
💬 Claude Sonnet chat on every transcript
Open any transcript and ask Claude — "summarize the key decisions", "pull every action item with timestamps", "what did Sarah say about churn?" — included on every paid pack. Conversations are saved to your account and deleted with it on our server, and Anthropic doesn’t train on them. With Realtime you’d wire your own model, your own prompt, your own bill.
📨 A human who answers your email
Email contact@neugence.ai and you reach the same person who built the product — typically same-day reply, no support-tier gate. OpenAI’s Realtime API ships with docs, a forum, and an enterprise contract for ticketed support. On Whipscribe a question about your file, your bill, or a feature request goes straight to a human who can fix it.

When ChatGPT Realtime Audio is the right call
- You’re building a voice agent that needs GPT-5 reasoning, tool calls, and barge-in. Realtime-2 is genuinely state-of-the-art here.
- You need live speech-to-speech translation in 13 target languages and want a single OpenAI endpoint instead of stitching Whisper + GPT-4o + TTS.
- Your audio is already in OpenAI’s ecosystem (Realtime API, Responses API, Assistants) and a separate vendor adds friction.
When Whipscribe is the better fit
- You want a transcript — TXT, SRT, VTT, DOCX, JSON — not a voice agent.
- You care about privacy: legal, medical, journalism, EU-residency, or anything subject to data-export rules.
- You want to try without signing up — paste a URL or drop a file and preview the transcript instantly; $0.99 opens your first one in full, no account needed.
- You need diarization out of the box, URL input, batch uploads, an MCP server, a ChatGPT Custom GPT, an Obsidian plugin, or a Mac desktop app.
- You want credits that never expire: after your free first transcript, pick a pack that fits ($8 / 1,000 min · $12 / 2,000 · $24 / 5,000) and use them today, next month, or a year from now. At the $12 pack the effective rate is $0.36/hr; at the $24 pack it’s about $0.29/hr — both well under the $1.02/hr Realtime-Whisper rate.
FAQ
Which one should I pick for my use case?
If you need a transcript file (TXT, SRT, DOCX) from a recording, an interview, a meeting, a podcast, or a YouTube link — Whipscribe is the right tool. Drop the file or paste the URL and read the transcript.
If you’re a developer building a live voice agent that needs GPT-5 reasoning, tool calls, and barge-in — ChatGPT Realtime-2 is the right tool. It’s an API, not a transcription product.
If you need live speech-to-speech translation across 70 → 13 languages with low latency — ChatGPT Realtime-Translate is built for that. Whipscribe transcribes; translation is a separate step.
Do I need to write code to use ChatGPT Realtime Audio?
Yes. All three models are developer APIs — you’ll need an OpenAI account, an API key, and code that opens an audio stream to api.openai.com. There is no web app and no upload form.
Whipscribe has a web app at whipscribe.com — paste a URL or drop a file and you get a transcript in seconds, no code. Preview any transcript instantly with no signup; $0.99 opens your first one in full, no account needed, at any length.
Can I transcribe a YouTube video or podcast URL with ChatGPT Realtime?
Not directly. ChatGPT Realtime accepts a raw audio stream — you’d need to download or capture the audio yourself and pipe it in. Whipscribe accepts a URL: paste a YouTube, Vimeo, podcast, or direct media link and the audio is fetched for you.
How much will I actually pay for typical workloads?
Realtime-Whisper is billed at $0.017 per minute, rounded to the nearest second.
- 1 hour / month — ChatGPT Realtime ≈ $1.02 · Whipscribe $0.99 for your first transcript, then the $8 / 1,000-minute pack covers it many times over
- 10 hours / month — ChatGPT Realtime ≈ $10.20 · Whipscribe $8 / 1,000-minute pack (covers it with room to spare)
- 40 hours / month — ChatGPT Realtime ≈ $40.80 · Whipscribe $24 / 5,000-min pack (≈ 3.5× cheaper per minute)
- 2,000 minutes / month — ChatGPT Realtime ≈ $34 · Whipscribe $12 / 2,000-min pack (≈ 2.8× cheaper)
Realtime-Translate at $0.034/min (≈ $2.04/hr) and Realtime-2 voice agent ($32 / $64 per 1M tokens) bill the same way — usage-metered, no monthly cap, no free tier.
Is my audio private with each tool?
ChatGPT Realtime Audio: every audio stream is sent to OpenAI’s servers in the United States and retained per OpenAI’s data-usage policy. Default API access is not HIPAA-eligible.
Whipscribe: audio is processed on Whipscribe’s own GPU cluster using self-hosted Whisper / whisperX. Audio is never sent to OpenAI or any third-party AI provider. Recordings are not used for training. The full posture is on /security and /privacy.
Does ChatGPT Realtime work for Zoom / Google Meet / Teams transcripts?
There’s no built-in meeting bot — you’d capture the meeting audio yourself, then stream it in. Whipscribe accepts uploaded recordings (mp4, m4a, mp3, wav and many more) and offers Live Meeting Notes in beta for browser-tab capture.
Which is more accurate?
Realtime-Whisper is the same Whisper family Whipscribe runs (whisper / whisperX). On clean speech the two are very close. Differences in the final transcript come from features layered on top: speaker diarization, word-level alignment, punctuation restoration, and language detection — all included on Whipscribe, not on Realtime-Whisper.
HIPAA / SOC 2 / EU data residency — what are my options?
OpenAI offers HIPAA via their Enterprise tier; default API access is not HIPAA-eligible. EU residency requires an OpenAI Enterprise contract.
Whipscribe runs on Neugence-owned infrastructure with self-hosted models and no third-party AI on the audio path. See /security for the current posture, certifications status, and how to request a DPA.
Can I use both together?
Yes — they solve different problems. A common pattern: use Whipscribe for the transcript (with diarization, timestamps, exports), then feed the text to GPT-5 / Realtime-2 to build a voice agent on top. The Whipscribe MCP server and the ChatGPT Custom GPT make that handoff one click.
Is there a free way to try either one?
ChatGPT Realtime Audio has no free tier — you pay from the first second.
Your first Whipscribe transcript is free, at any length. Preview any transcript instantly with no signup; $0.99 opens your first one in full, no account needed. After that, credit packs start at $8 for 1,000 minutes, and credits don’t expire.
Whipscribe is a managed faster-whisper + whisperX service — privacy-first, first transcript free, then credit packs from $8 / 1,000 min up to $24 / 5,000 min (credits never expire), no API key to try, 99 languages, speaker labels included.
