Turn a voice memo into a
send-ready email in under a minute.

audien·to is an AI audio tool that turns a voice memo into a send-ready email — subject line, opener, body, sign-off — in about 10 seconds. Unlike generic transcription that gives you a wall of text, it shapes your spoken thoughts into the exact format your recipient expects. Free tier, 67 languages, no signup.

Talk out what you want to say — rambling is fine. We’ll write a tight subject line, a proper intro, the body in your voice, and a sign-off. Paste straight into Gmail, Outlook, or Superhuman.

The guide

Why turn a voice memo into an email

Talking is faster than writing — maybe 3× faster — and you cover everything that’s actually on your mind. Typing it up afterward is the part you keep putting off.

This tool exists so you can talk your message out and send it. Your tone gets preserved; the filler and detours get trimmed. Good for replies you’ve been avoiding, tough messages, or end-of-day status updates.

What a good email from a voice memo looks like

  • Subject line — short, specific, readable in an inbox preview.
  • Greeting — matches how you’d actually open a message.
  • Body — your point, in your voice, minus the rambling.
  • Sign-off — the closing that sounds like you.

How audien·to structures yours

What lands in the doc

  • Subject line≤8 words, scannable in an inbox preview, describes the outcome rather than the topic.
  • Greetingmatches how you usually open — “Hey Lorenzo,” “Hi team,” or just the name.
  • Bodyyour message in your voice, with rambling, restarts, and tangents trimmed.
  • Sign-offyour usual close (— Ada / Thanks / Cheers) — pulled from your prior style or a default.
  • Optional follow-up lineif you mentioned a date, a one-liner reminding the recipient when you’ll check back.

Writing the email well

  • Subject describes outcome“Approved: Q2 budget” beats “Budget update.” The recipient should know the answer before opening.
  • Skip the apologyif you’re not actually sorry, don’t open with sorry — it weakens what follows.
  • One ask per emailif you have two, send two. Mixed asks get mixed answers.
  • Read it as the recipientwould they reply, or skim and forget? If skim — shorten.
  • Match their registerif they write in two-line emails, send a two-line email back. Mirroring builds rapport faster than effort.

Knobs in the Options panel

  • Tonewarm · neutral · direct · formal — defaults to your memo’s register.
  • Lengthtight (3 sentences) · standard · detailed (≤200 words).
  • Salutation stylefirst-name only · “Hi [Name],” · formal (“Dear [Name],”).
  • Sign-offyour usual close · context-appropriate (formal / casual) · none.
  • Filler trimaggressive (default — sentences only) · light (keep your asides) · off (verbatim).
  • Subject styleimperative (“Move launch to Monday”) · question · outcome-led.

How to judge what came back

Read the draft as if it just landed in your inbox from someone else. If you'd hesitate to reply, send it back to the model with a fix from the next section.

  1. Would you click the subject from a phone preview?
    Fail: subject is generic (“Quick update”) or buries the ask. Good subjects describe the outcome the recipient cares about.
  2. Does the greeting match the actual relationship?
    Fail: “Dear Lorenzo” to a teammate, or first-name-only to a board member. The opener sets the register for everything that follows.
  3. Is there exactly one ask?
    Fail: two unrelated requests sharing a body. Mixed asks get mixed answers; split into two emails before you send.
  4. Could you read it on a phone in under 10 seconds?
    Fail: dense paragraphs, no white space, or a wall of context before the ask. Move the point to the first line.
  5. Does it sound like you?
    Fail: stiff phrases you'd never say (“Per my last email…”, “Kindly advise…”). The model should mirror your voice from the memo, not impose a corporate one.
  6. Did it invent any facts?
    Fail: dates, names, or commitments that weren't in your memo. AI shouldn't fill blanks — if you didn't say it, don't send it.
  7. Is the sign-off something you'd actually type?
    Fail: “Best regards,” for a casual peer, or “Cheers!” to your CEO. Match the close to the same register as the greeting.

Refine it further

If the first draft is close but not quite there, paste one of these into the Custom instruction box and re-run. Each is short on purpose — the model handles edits better than rewrites.

Tighten
  • Cut the body to 3 sentences max.
  • Remove the second paragraph entirely — keep the ask in one line.
  • Make the subject 5 words or fewer.
  • Drop every adverb (really, very, just, actually).
Re-pitch the tone
  • Use “Hey” not “Hi.” Match how I talk to peers.
  • Sound warmer — start with one sentence acknowledging their last reply.
  • Sound more direct — open with the ask, context after.
  • Drop the apology — I'm not actually sorry, just stating the change.
Sharpen the ask
  • Make the ask explicit in the first sentence.
  • Add a specific date and time I'll check back if I don't hear from them.
  • Rephrase the ask as a yes/no question so they can reply in one word.
  • Add a deadline. If I didn't say one, suggest “end of this week.”
Match the recipient
  • The recipient writes 2-line replies. Match their length.
  • This is going to a customer, not a teammate. Adjust the register.
  • Assume they haven't read the prior thread. Add one sentence of context.
  • They prefer bullet points. Reformat the body as 3 short bullets.
Fix the subject line
  • Rewrite the subject to describe the outcome, not the topic.
  • Make the subject a question they'll want to answer.
  • Lead with “Re:” and the original subject if this is a reply.
  • Add a date to the subject (e.g., “— Mon”) if timing matters.
Why this works

Why modern AI hears what older tools missed

When you upload audio, two AIs go to work. The first one listens. It learned from millions of hours of real speech — accented, overlapping, full of “ums” and brand names that didn’t exist five years ago — so it can hear “Klaviyo,” “Substack,” or “the GPT pipeline” without flinching. The words older tools used to silently mangle come back right.

It hears in context. Instead of guessing one sound at a time, it takes in the whole sentence and uses everything around a tricky word to figure out what was actually said. That’s how a brand-new product name still lands correctly: the words around it tell the AI what kind of sentence it’s in.

And it cleans as it goes. Disfluency — “uh, like, I think… yeah” — doesn’t drop the rest of the sentence on the floor. Punctuation and capitalization come built in, so what you read is prose, not a wall of lowercase. By the time it hands off, the transcript already looks like what a careful typist would have given you.

What happens once we have your words

A raw transcript is the floor, not the ceiling. The second AI reads the whole document the way a careful editor would. It groups related discussion into chapters even when nobody says “moving on.” It surfaces the quote you’d actually screenshot — not the longest sentence on the page. It separates a decision from a tangent, an action item from a passing wish.

That’s the jump older tools couldn’t make: they gave you words, we give you shape. A meeting becomes minutes with owners, dates, and resolved questions. A podcast becomes show notes whose chapters track the real narrative, not the nearest five-minute mark. A voice memo becomes a send-ready email in your voice — not a list of fragments to stitch back together.

Each tool on this page is one of those pairings — the same listening AI up front, the same writing AI behind it, shaped for one specific output. You don’t pick. You don’t tweak. A thirty-second upload comes back as the thing you actually wanted, ready to use.
