How to Record Your Own Walk-Up Announcer Voice

A practical guide to making stadium-style intros that sound the part — equipment, script formats, recording technique, and a 60-second shortcut if you don't want to bother with the setup.

The case for recording it yourself

AI announcer voices have come a long way and are perfectly fine for most teams. But there's a specific reason a coach or parent might want to record their own: the personal touch matters at the youth level. A grandparent's voice introducing their grandkid, a coach giving a personalized intro to each player, a teammate recording each other's intros for an end-of-season tournament — these moments carry weight that an AI voice doesn't. They become memories.

This guide walks you through doing it well. The whole process takes 30-60 minutes for a 12-player roster.

The 60-second version (skip the rest if this fits)

If you have OnDeckDJ installed and don't want to deal with audio software:

  1. Open OnDeckDJ → tap any player → tap the announcer voice section.
  2. Choose "Record Your Own".
  3. Tap record, deliver the announcement (3-5 seconds), tap stop.
  4. Trim the silence using the in-app trimmer.
  5. Save. Repeat for the rest of the lineup.

That's the easy path. Total time: about 90 seconds per player. The rest of this article is for people who want to do a more polished, studio-quality version that they can use across multiple seasons or share with other coaches.

What you actually need

A microphone

You don't need expensive gear, but you do need something better than your laptop's built-in mic. Three tiers:

Recording software

You don't need a paid DAW for this. Three free options that work great:

A quiet room

Sound treatment matters more than your mic choice. Record in a closet full of clothes, under a blanket fort, or in a small carpeted room. Avoid: kitchens, bathrooms (too much echo), rooms with hard floors and bare walls. A few seconds of being thoughtful about the room beats $200 of mic upgrades.

Writing the script

The format that works best for youth baseball walk-ups:

"Now batting, number twenty-three, Bryce Harper."

Three components, in this order. Why it works:

Keep it under 5 seconds. Anything longer eats into the song's walk-up window. If you have a player with a long name (e.g., "Alessandra Rodriguez-Fernandez"), shorten the announcement: "Now batting, number 12, Alessandra."

Variations to consider: "Coming to the plate, your shortstop, number 7, Maya Chen." — adds position. "From Springfield, Missouri, number 4, Tyler Johnson." — adds hometown. Both work for tournament settings; both are slightly long for regular-season games.

How to actually deliver the line

This is the part most DIY recordings get wrong. A few rules:

1. Project, don't shout

Imagine you're announcing to a crowd of 50 people in an outdoor space — not yelling, but reaching the back row. Speak from your diaphragm. If you whisper or speak too softly, the recording will need to be amplified post-production, which adds noise.

2. Pause where the punctuation pauses

Stadium announcers naturally drop a beat between each phrase: "Now batting... [pause]... number twenty-three... [pause]... Bryce Harper." The pauses give the words weight and let the listener process each piece of info.

3. Stretch the name

The single most-recognizable trait of stadium announcing is the elongated final syllable on the last name. "Bryce HAR-PER," with emphasis and length on the last syllable. Try a recording without it, then with it. The difference is dramatic.

4. Record multiple takes

Don't try to nail the announcement in one take. Record 3-5 versions of each player's intro, then pick the best one. Different intonations work differently for different songs — having options means you can match the announcement to the song's energy.

5. Stay consistent across players

If you say "Now batting" for one player, say "Now batting" for every player. If you stretch the name on one, stretch the name on all. Inconsistency in the announcement style is more jarring than any individual flaw in a single recording.

Post-production: trimming and polishing

1Trim silence at the start and end

Every recording needs the dead space at the beginning and end removed. The announcement should start within 0.1 seconds of audio playback and end immediately after the final word. In Audacity or GarageBand, this is just selecting the silence and pressing delete.

2Normalize volume

Use the "Normalize" or "Compressor" effect in your software. Target -3 dB peak level. This makes sure all your announcements play at consistent volume — without it, one will sound loud and the next quiet.

3(Optional) Add light reverb

Stadium announcements have a tiny bit of echo because they're playing through a PA in an open space. To simulate this, add a "small room" or "stadium" reverb at low intensity (about 10-15% wet). Don't overdo it — too much reverb sounds like a school auditorium recording, not a major league ballpark.

4(Optional) High-pass filter

Cut everything below 80 Hz with a high-pass filter. This removes low-end rumble (HVAC, room hum, traffic noise) without affecting the voice. Most recording software has this as a one-click effect.

5Export as MP3 or WAV

Export each player's announcement as a separate file. MP3 at 192 kbps is fine for walk-up audio. Name the files clearly: announcement_harper_23.mp3, announcement_chen_7.mp3, etc.

Skip the setup. Use OnDeckDJ's built-in recording.

Tap, talk, trim. Same end result, none of the audio engineering. Free to start.

Get OnDeckDJ on the App Store

Importing into OnDeckDJ

Once your recordings are processed, import them into OnDeckDJ:

  1. AirDrop or email each MP3 to your iPhone.
  2. Open OnDeckDJ → tap a player → in the announcer section, choose Custom Audio instead of an AI voice.
  3. Pick the right MP3 from your Files app.
  4. Preview to confirm timing. Save.

The custom recording now plays in place of an AI announcer — same volume ducking, same Game Mode flow, same one-tap experience. The only difference is that it's your voice.
