Voice Chk generates spoken audio from text: phone greetings, voicemail messages and IVR prompts, in the formats a phone system actually accepts. It exists because every business that changes its opening hours needs a new greeting, and almost none of them have a way to make one.
How it works
Audio generation
Text is converted to speech with a selectable voice, and the result is offered for download.
Telephony formats
Output can be converted to the encodings phone systems expect, which is what separates a usable prompt from an audio file a PBX will refuse.
FFmpeg
The format conversion needs FFmpeg installed on the server. Without it, generation still works but the telephony formats are unavailable.
Requirements
- WordPress 5.8 or newer
- PHP 7.4 or newer
- FFmpeg installed on the server, for the telephony output formats
- An API key for the text to speech provider you choose
Publishing it
Drop one of these shortcodes on any page or post. Each one is self-contained and needs no theme integration.
[voice_chk][voice_forge]
Attribution. The plugin shows a small “A tool by Digital Checkmark” line, with a link to digitalchk.com, under the voice generator and under every email it sends. It is part of the plugin and has no setting to turn it off. If a tool and a Leads Chk form share a page, the line shows once.
Setup
Anti-abuse Recommended
Under Settings, add your Cloudflare Turnstile site key and secret key. Without it, anyone can script the public tool and consume your quotas on the outside services it uses.
With the keys in place, the plugin also refuses to email a verification code or a report unless the visitor recently passed a Turnstile check. A normal search counts; if not, a small check window opens before sending.
Email verification Recommended
The plugin verifies in three layers before sending a report: format, disposable domain, and, if you add a Reoon key, a real deliverability check. This protects your sending reputation from bounces to invented addresses.
PDF reports Optional
Reports are converted to PDF by Gotenberg, which you self-host. Set its URL in the reports tab; on the same machine that is http://127.0.0.1:3000. Without Gotenberg the rest of the plugin works unchanged.
Delivery and branding
Configure the SMTP server that sends the reports and the branding that appears on them: name, tagline, logo, colors and cover.
Notifications and contacts Optional
It can notify you by email or webhook when a lead arrives and, if you use Leads Chk, hand that lead to it, which keeps your contacts and your newsletter. Everything filters by event and by source, so you are not paged for noise.
Usage wall with a code Optional
Free uses are counted on the server, and you choose how many, so a private window does not reset them. Past the limit the visitor confirms an email address with a 6-digit code, and the tool unlocks for the rest of the day. Code requests and wrong attempts are limited, with a temporary lock. An address nobody verified is never saved as a lead.
Download with email Optional
Visitors listen to a preview first. To download the file they confirm an email address with the same 6-digit code as the usage wall, and a verified visitor downloads directly for the rest of the day. If you want, the preview can carry a soft tone every 3 seconds so the player cannot give away the clean file (off by default, because it can make the voice sound faulty). The server never hands out the file without the code, and each download is saved as a lead with the source Download.
Lead capture and retention
When somebody asks for their report, the plugin stores the address as a lead along with a summary of the result. You will find these under Leads, and they export to CSV.
Retention is governed by GDPR Retention (days): leads older than that are deleted automatically by a scheduled task. Set it to 0 to disable the purge, though we would not recommend it. Declare in your privacy policy what you store and for how long.
The plugin also works with the WordPress privacy tools (Tools > Export Personal Data and Erase Personal Data): one request exports or deletes everything it keeps for an email address, together with the other Digital Checkmark plugins you have installed.
If Leads Chk is installed, every address the plugin collects through a report, the usage wall or the access gate is also sent there, with tags (the tool, how the address arrived, business or personal, and the result) and a consent record. What happens next (saved only, newsletter offered with a checkbox, or subscribed) and which list it goes to is decided in this plugin’s Integrations screen. Addresses that were only looked up, and could belong to someone else, stay out of Leads Chk. Leads Chk can also place a newsletter form under the tool.
If something does not work
Audio generates but the telephony formats are missing.
FFmpeg is not installed or not on the server’s PATH. The Info tab reports what it detected.
