Abstract

Embodiments of the present disclosure provide a method of on-site speech broadcasting. The method includes receiving text signal, wherein the text signal is generated in response to a parameter reaching a predetermined value sensed by an on-site sensor (110) arranged in the field; converting the text signal to a speech signal by a speech converting module (210) disposed within an on-site speaker device (200); playing the converted speech signal by using a speaker (220) of the on-site speaker device (200). Embodiments of the present disclosure also provide an on-site speaker device and an on-site speech broadcasting system. With the embodiments of the present disclosure, an effective text-to-speech conversion is achieved, pre-created speech data is not necessary and the workload of design is reduced, making it more cost effective. Meanwhile, speech messages being broadcasted allow operators instantaneously knowing the content of the alarm. Therefore, the operators are able to position and tackle the problem right away, improving efficiency and safety.

Claims

1. A method of on-site speech broadcasting, comprising:

receiving a text signal, wherein the text signal is generated in response to a parameter sensed by an on-site sensor reaching a predetermined value;

converting the text signal to a speech signal by a speech converting module disposed within an on-site speaker device; and

playing the converted speech signal by using a speaker of the on-site speaker device.

2. The method according to claim 1, wherein the text signal is generated by selecting from a plurality of texts preset by the user in response to the parameter sensed by the on-site sensor reaching the predetermined value.

3. The method according to claim 1, further comprising inserting a mark in the text signal, the mark indicating a requirement of text-to-speech conversion, such that the speech converting module converts the text signal to the speech signal in accordance with the requirement.

4. The method according to claim 1, wherein the text signal comprises at least two languages.

5. An on-site speaker device, comprising:

a receiving interface for receiving a text signal, wherein the text signal is generated in response to a parameter sensed by an on-site sensor reaching a predetermined value;

a speech converting module for converting the text signal to a speech signal; and

a speaker for playing the speech signal.

6. The on-site speaker device according to claim 5, wherein the speech converting module is capable of converting the text signal to the speech signal in accordance with a requirement of text-to-speech conversion indicated by a mark in the text signal.

7. The on-site speaker device according to claim 5, wherein the text signal comprises at least two languages.

8. An on-site speech broadcasting system, comprising:

a text generating device for generating a text signal, having;

a sensor capable of sensing a parameter reaching a predetermined value;

a human machine interface for generating the text signal in response to the parameter sensed by the sensor reaching the predetermined value; and

a transmitting interface for transmitting the text signal; and

an on-site speaker device including;

a receiving interface for receiving the text signal;

a speech converting module for converting the text signal to a speech signal; and

a speaker for playing the speech signal.

9. The on-site speech broadcasting system according to claim 8, wherein the text generating device is configured to generate the text signal by selecting from a plurality of texts preset by the user via the human machine interface in response to the parameter sensed by the sensor reaching the predetermined value.
