through the use of IP Multimedia Subsystem (IMS) [9] or until IMS is available through the current IP and mobile packet switched networks as suggested by the TCAM eWG [32]

188.97Regardless of the transport method, the same AT command can be used.

188.989.16 Text-to-speech


Users shall be given the option to enable text-to-speech (TTS) on their communication device. For users with visual impairments, text-to-speech is a useful functionality. Settings for speech rate, spelling speed and number read-out (options for how numbers larger than four digits will be read) and language option will be available.

In order to specify the natural language that is used by the text-to-speech (TTS) functionality, the parameter language is used. It is defined as specified by the ISO standard for the "representation of names of languages", ISO 639 [ 22, 23]. The language codes are based upon the concept of a set of basic languages together with variants based upon the country in which they are used (e.g. French used in France is coded as "fr-FR, and when used in Canada is coded as "fr-CA").

Further enhancements on multicultural and language aspects might be relevant to address in the future. These enhancements shall be based on the guidelines and suggested future work described in EG 202 421 [2]

Text-to-speech

Recommendation 9.16.a: The communication device shall provide an interface with the necessary AT command to allow an external to enable text-to-speech on their communication device.

Recommendation 9.16.b: The communication device shall provide an interface with the necessary AT command to allow an external device to set speech rate.

Recommendation 9.16.c: The communication device shall provide an interface with the necessary AT command to allow an external device to set spelling speed.

Recommendation 9.16.d: The communication device shall provide an interface with the necessary AT command to allow an external device to select how numbers larger than four digits will be read.

Recommendation 9.16.e: The communication device shall provide an interface with the necessary AT command to allow an external device to specify the natural language that is used by the text-to-speech functionality.

The technical report on "Requirements for assistive technology devices in ICT" [1], has identified the need for redefining time-outs, which shall allow the user more time to perform various actions.

Time-out

Recommendation 9.17: The communication device shall provide an interface with the necessary AT command to allow an external device to redefine the time for a range of time-outs, for various actions.
