Text-to-speech: Have important SMS read out to the recipient by phone call

Send very important messages via text-to-speech to mobile phones but also to landline phones. eCall can convert SMS messages that need to reach recipients quickly and reliably into voice messages.

This is how Text-to-Speech (TTS) works with eCall:

eCall converts the written text to speech, calls the recipient and reads the message to them. Text-to-Speech SMS can be sent directly from your eCall account or via an interface (API). This function is supported worldwide, including confirmation of receipt. In addition, you can forward incoming SMS as a voice message via a phone call.

The system automatically recognises the language of the written text and outputs it in the corresponding language version: German, English, French or Italian. In addition, the “High Privacy Voice” feature is available on request, in which all contents are overwritten after processing.

Four exciting areas of application for the use of SMS-to-Voice

  • Important messages such as the delivery of access codes, activation PINs, mTANs, etc. After the message has been received, it can be listened to again.
  • Urgent messages that the recipients must not miss under any circumstances – such as for staff scheduling and coordination. If the recipient cannot be reached, the system repeats the message twice with an interval of five minutes.
  • In the alerting area, where technicians need to be reliably and quickly informed about critical malfunctions or measured values. Reception can be confirmed manually.
  • This can be useful for people with visual impairments because the system calls the recipient and reads the message to him or her.

eCall tip: «Forwarding SMS as a voice message via a phone call»

SMS messages received with a virtual mobile phone number rented from eCall can be converted by the system into a text-to-speech message and forwarded as a telephone call to any telephone number. The system automatically recognises the text in the languages DE, EN, FR and IT and reads the message to the recipient.

This feature is ideal for use in an alerting scenario but also anywhere very important messages need to reach recipients quickly and reliably.

SMS read aloud as a voice message also for people with impaired vision

Voice messages can be sent to any mobile or landline phone. The service is supported worldwide. The system calls the recipient and reads the message to them. This can be useful for people with visual impairments. After receiving the message, the message can be listened to again and the receipt confirmed manually. If the recipient is not reachable, the system repeats the message twice with an interval of five minutes.

Read aloud mTANs and other security codes

eCall also sends mTANs as text-to-speech on request. For 2-step authentication, confidential information such as mobile transaction numbers or access codes can also be transmitted as voice messages via call.

Two key benefits of voice messages:

A call always reaches its destination. In the case of text messages, there may be delays in delivery in international traffic, depending on the provider and the recipient’s country.

► We are the only provider that protects voice messages with an additional security feature. With the High Privacy Voice option, the system overwrites the message so that it cannot be reconstructed after transmission.

eCall saves the landline SMS

From 1 July 2018, sending and receiving text messages to landline numbers is no longer readily available. Swisscom has discontinued the “landline SMS” service. Receiving SMS on a landline number is now only possible if the message is sent directly to a mobile phone number – or if it is sent using eCall.

With the eCall SMS-to-speech service, you can still send SMS messages to landline phones. The system detects whether the recipient is a landline number and delivers the message as an audio message. SMS from technical devices (such as sensors, modems or similar) can also be received and forwarded by eCall accordingly.
