Text-to-Speech – reading text messages and landline SMS aloud by eCall

Landline SMS: Our system converts written text messages into speech, calls up the recipient and “reads” the message text. Text-to-speech messages can be sent directly from your eCall account via the Web interface or via API interface. The system identifies the written text and automatically converts it into speech in the desired language (German, English, French or Italian). >> Try our service free of charge

SMS read aloud even for people with impaired vision

These voice messages can be sent to any cellphone or landline. The service is globally supported. The system calls up the recipient and “reads” the message text. This can be a boon for the visually impaired. After receipt, the message can be listened to again and receipt confirmed manually. If the recipient is unavailable, the system repeats the message twice more at a five-minute interval.

eCall saves the landline SMS

eCall transmits an audio message.

On July 1, 2018 Swisscom switched off the "Landline-SMS"-service after more than 12 years. So far a text message sent to a fixed line number was converted automatically into a voice message and was read out loud to the recipient.

With the eCall SMS-To-Speech-Service it is still possible to send text messages to fixed devices. The system recognizes if the recipient's number is a landline and transmits an audio message in german, french, english or italian language.Furthermore eCall is able to receive and forward messages from technical devices (such as sensors, modems etc.).

Read out mTANs

On request, eCall can also send mTANs as text-to-speech. Confidential information such as mobile transaction numbers (mTANs) or access codes can also be sent as voice messages in two-level authentication. 

Voice messages have two key benefits: 

  • eCall always reaches its recipient. However, text messages may experience delays in international transmission, depending on the provider and the recipient’s country.
  • We are the only provider to offer additional security protection for voice messages. The “High Privacy Voice” option overwrites the message, preventing it from being reconstructed.

We are looking forward to your contact request
