Live data-to-speaker announcements

Live event announcements from your data - in seconds.

Yobikoe turns schedules, rosters, spreadsheets, databases, and APIs into clear spoken announcements. Preview, queue, and play them through your venue speakers.

How it works

From live data to the loudspeakers - in 4 steps.

Live calls, in seconds
Pick a template, select the live item, and create the announcement. Competitor names, locations, categories, and timing are filled automatically.
Bound to your data
Connect spreadsheets, databases, or APIs once. When the source changes, the next announcement uses the latest data without manual rewriting.
Scan, and go
Scan a printed schedule or roster barcode and Yobikoe shows the exact templates for that category, match, gate, platform, or zone.
To the whole venue
Preview the audio, queue it, and play it live from the web app in a browser or through an RTSP stream for your venue AV setup.

Natural AI voice

Natural AI voices for multilingual venues.

Generate clear announcements in up to 74 languages. Yobikoe pronounces names and countries natively, so international guests understand every call. Multilingual content stays natural when your schedule mixes teams, places, categories, and instructions. You can add sound effects and speech directives to match the moment.

Use cases

If it has to be announced, Yobikoe says it.

Sports competitions

Runners racing down a track as results come in — The instant a heat ends, the result has to reach the stands. Yobikoe turns finish-line timing data into clear winner, lane and next-up calls - without anyone reading every line off a sheet.

Stadiums & arenas

A full football stadium under floodlights during a match — Line-ups, scores, safety notices. Yobikoe gives a packed bowl a natural voice the second the data changes - between every play and at full-time.

Transit hubs

A station departure board listing upcoming trains — When a platform or delay changes, seconds matter. Yobikoe reads live departure and gate updates aloud the moment they post - consistent and multilingual, all day long.

Expo halls

A speaker on stage addressing a full conference hall — Keynotes, hall changes, last call for a session. Yobikoe runs both scheduled and ad-hoc announcements across the floor without tying a person to a microphone.

Theme parks

A busy fairground at dusk with a lit ferris wheel — Ride re-openings, parade times, queue updates. Yobikoe keeps guests informed zone by zone with a friendly voice that never tires, sent straight from your operations data.

Can announcements be customized for our event?

Yes. Yobikoe templates can be fully customized to the needs of each event, including the wording, languages, data fields, categories, timing, sound effects, and playback workflow.

Do we need technical staff to use Yobikoe?

No. Event staff can use Yobikoe through simple templates, previews, queues, and barcode scans. The technical setup can be prepared before the event, and we help configure it for your workflow.

How does Yobikoe use live event data?

Yobikoe connects templates to data sources such as spreadsheets, databases, or APIs. When the source data changes, the next announcement uses the latest names, locations, categories, times, gates, platforms, or zones without manual rewriting.

What kind of data sources can Yobikoe use?

A data source can be as simple as an uploaded spreadsheet. For more advanced events, Yobikoe can also pull data from APIs using simple programming inside the app, so announcements can follow your event system or schedule data.

Will you help us set up Yobikoe for an event?

Yes. We help configure templates, data sources, languages, barcode behavior, and playback for the event, so the team can operate Yobikoe without needing to design the setup from scratch.

How do barcode-triggered announcements work?

Barcode workflows are flexible. A scan can show the right templates for an operator to choose from, add an announcement to the queue, or trigger a fully automated scan-and-play announcement depending on how the event should run.

Can barcode scanning make announcements semi-automated or fully automated?

Yes. Yobikoe can be configured for semi-automated workflows, where scanning prepares the correct announcement for review, or fully automated workflows, where a scan immediately creates and plays the announcement.

Can Yobikoe announce names and countries in multiple languages?

Yes. Yobikoe generates natural AI voice announcements in up to 74 languages and can pronounce names, countries, and multilingual content so international audiences hear clear, prepared calls.

Does Yobikoe require a recording studio or voice actor?

No. Yobikoe generates speech from templates and live data, so venues do not need studio recording, voice actors, or audio engineers for routine announcements.

How are announcements played or streamed?

Yobikoe can play announcements directly from the web app in a browser, or provide an RTSP audio stream for venues that want to route announcements into an existing AV or broadcast setup.

Is Yobikoe only for karate or sports events?

No. The showcase video demonstrates a high-volume live event, but the same system fits transit updates, arena calls, expo hall instructions, theme park messages, retail announcements, and other venue communication.
