The player you embed on your site carries your colors, fonts, and logo, and you can control what it shows and how it starts. Branding is set once in the dashboard and applies to your embeds. Playback behavior is set per embed with URL parameters.

Brand the player
Open Shared Media → Settings → Branding & Customization and set:
- Primary color for buttons and highlights, and the font color
- Theme, either light or dark as the base
- Font family, chosen from the available fonts, so the player matches your site
- Logo and background image, uploaded from your own files
- Waveform, hidden if you want a plainer player
- Title and description, hidden if the surrounding page already says what the recording is
- Insights, ticked one by one to choose which appear next to the recording
- Downloads, allowing viewers to download your data visualizations
- Search engine indexing, allowing the shared page to be indexed
- Call to action, a button that sends viewers where you want them to go next
Click Save when you are done. Changes apply to your embedded players.
Custom CSS
For control past those settings, use the Custom CSS field in the same settings screen. Enter standard CSS to override specific styles:
.sp-recorder-btn {
border-radius: 20px;
font-weight: bold;
}The player updates as you type.
Set the starting state with URL parameters
Append parameters to the embed URL to control how the player loads:
?autoplay=truestarts playback automatically, if the browser allows it?t=120starts playback at a set time in seconds, here two minutes?hideWaveform=truehides the waveform
Side by side layout
To put the player and the transcript side by side, add isHorizontal=true with the width you want for each panel. The two widths are percentages and have to add up to 100:
https://embed.speakai.co/iframe/your-media-slug?isHorizontal=true&playerWidth=70&transcriptWidth=30Find the src on your iframe and add the parameters to the end of that URL. This layout applies to iframe embeds only.
React to player events
The embed sends messages to the page around it using the browser postMessage API, so you can pause, play, or react from your own code:
readyfires when the player has finished loadingfinishfires when playback has completed
If your security policies block these messages, add your domain to the allowed list in the recorder settings.
