## Abstract

In one aspect, the present application is directed to a computer-implemented method, a mobile device, a computer network system, and a computer-program product for optimized audio data provision. In an aspect, a computer-implemented method for optimized audio data provision on mobile devices is provided. The method may comprise: evaluating one or more parameters of a network connection of a mobile device; and depending on said evaluation, automatically switching between downloading audio data in an audio file from a server in real-time and downloading audio data in a text file from the server and performing a text-to-speech application of audio data on the mobile device.

## Claims

### Claim 1

A method comprising:
evaluating, by a mobile device, one or more parameters of a network connection associated with the mobile device,
the network connection relating to a connection of the mobile device to a network for access of a server;
determining, by the mobile device, a signal strength of the network connection based on evaluating the one or more parameters;
setting, by the mobile device, a threshold speed based on the signal strength of the network connection;
downloading, by the mobile device, a test file from a server device,
the test file having a pre-defined size;
measuring, by the mobile device, a download speed of the test file;
determining whether the download speed of the test file satisfies the threshold speed; and
selectively downloading, by the mobile device and based on whether the download speed of the test file satisfies the threshold speed, audio data,
the audio data being downloaded as an audio file, from the server device, when the download speed of the test file satisfies the threshold speed, and
the audio data being downloaded as a text file, from the server device, and the text file being converted to the audio data, via a text-to-speech application, when the download speed of the test file does not satisfy the threshold speed.

### Claim 2 (depends on 1)

The method of claim 1, further comprising:
determining a signal quality of the network connection based on evaluating the one or more parameters.

### Claim 3 (depends on 1)

The method of claim 1, further comprising:
identifying a change to the signal strength of the network connection based on evaluating the one or more parameters; and
determining whether the change to the signal strength of the network connection is greater than a pre-defined value.

### Claim 4 (depends on 1)

The method of claim 1, further comprising:
determining a connectivity type of the network connection based on evaluating the one or more parameters.

### Claim 5 (depends on 4)

The method of claim 4, where the connectivity type of the network connection is associated with a first network speed, and the method further comprises:
downloading the audio data as the text file when the first network speed satisfies the threshold speed; and
converting the text file to the audio data via the text-to-speech application.

### Claim 6 (depends on 1)

The method of claim 1, where the method is implemented by a mobile application provided on the mobile device.

### Claim 7 (depends on 1)

The method of claim 1, where instead of evaluating the one or more parameters, the method comprises:
receiving, by the mobile device from the server device, information associated with an evaluation of the one or more parameters,
the evaluation of the one or more parameters being performed by the server device.

### Claim 8

A mobile device comprising:

set a threshold speed based on the signal strength of the network connection;
download a test file from a server device,
the test file having a predetermined size;
measure a download speed of the test file;
determine whether the download speed of the test file satisfies the threshold speed; and
selectively download, based on whether the download speed of the test file satisfies the threshold speed, audio data,
the audio data being downloaded as an audio file, from the server device, when the download speed of the test file satisfies the threshold speed, and
