TTS AutodialerText-to-Speech Autodialer · Voice campaigns
Personalised voice messages, thousands of calls at a time
The Text-to-Speech Autodialer calls a list of customers and plays each one a message spoken in a natural neural voice, with their own details in it. Use it for payment reminders, collections, appointment reminders, alerts and announcements. No recording studio, no agents on the phone.
“Hello {name}, this is {institution}. Your account {account} has a balance of {balance}…”
How a campaign runs
- Create: name the campaign, then set the institution, caller ID, language (English, Swahili or both) and voice gender.
- Write: type the message using variables: {name}, {institution}, {account} and {balance}.
- Upload: import the leads CSV. Rows with a missing name, phone, balance or institution, invalid numbers and duplicates are skipped and can be exported.
- Generate: the system builds each contact's audio from reusable segments. A message it has already generated is reused without another speech API call.
- Dial: calls go out in parallel within your schedule, and unanswered calls are retried.
- Neural voicesMale and female voices in British English and Kenyan Swahili.
- Bilingual campaignsEnglish, Swahili or both on the same call.
- PersonalisationName, institution, account and balance spoken per contact.
- Smart audio cachingRepeated phrases are generated once and reused, which cuts speech costs.
- Lead validationMissing fields, invalid phones and duplicates are caught at upload.
- Parallel diallingConcurrency limits keep trunks within capacity.
- Automatic retriesFailed or unanswered contacts are re-tried up to a limit.
- SchedulingGlobal or per-campaign calling hours and days, with automatic pause and resume.
- Live monitorWatch progress: answered, pending and failed (no answer, busy, early hang-up).
- ReportsDownloadable campaign reports, plus DIDs, trunks, users and test calls.
