Problems solved by technology

[0004] First, in the process of system integration, two sets of interfaces are usually used to call and play prompt tone and synthesized voice respectively. In the case of relatively complex services provided by the telephone voice system, especially when prompt voice and synthesized voice appear alternately, In the case of frequent switching, the writing of business processes is particularly complicated, which also increases the workload of integrated development
[0005] Second, prompt voices are generally stored and managed in the form of voice files. A voice prompt is saved as a voice file, and generally needs to be converted from a certain voice data format to a specified voice data format. The number of files is large, and management is inconvenient. Matching It is also difficult, and it is...

Embodiment Construction

[0048] A method for synthesizing and outputting prompt sounds and text speech in a speech synthesis system, comprising first providing synthesized text information to the synthesis system by the user, and the synthesis system undergoes text analysis (sentence and word segmentation processing on the text) and prosodic analysis (generating volume, pitch, intonation, etc. of reading aloud), then call the pronunciation unit in the sound bank, be combined into continuous synthesized text speech data, it is characterized in that: set up prompt sound storehouse, set up sign (serial number or name) and prompt tone content For the corresponding prompt tone index, program content such as adding, deleting, volume adjustment, text content editing and management operations to the prompt tone bank is added in the resource management center of the speech synthesis system; the user development interface provided by the speech synthesis system In the function of setting synthesis parameters (in...

Abstract

In this method, a customer supplies the synthetic information to the synthesis system. The synthesis system, by analyzing the text and the rules of the rhyming and applying the pronunciation element in the library, combines the text with sound data. The invention constructs the prompting sound library to set the prompting sound parameter at the customer-developing interface of the sound synthesis system. The customer can add the expected prompting sound into the library to achieve the universal management of the prompting sound.

Description

technical field [0001] The invention relates to the field of speech synthesis, in particular to a method for managing and applying prompt speech during the conversion process from text to natural speech by using a computer. Background technique [0002] In telephone voice systems such as IVRs and call centers, business processes often require the use of pre-recorded prompts and synthetic voices at the same time. The pre-recorded prompts are recorded by real people, the effect is natural, and it can reflect more emotional styles, giving users a cordial feeling. Although the synthetic voice is clear and accurate, there is still a certain gap between the tone and emotion of the real person recording. In a specific application, the pre-recorded voice is used to broadcast relatively fixed content in the voice service system, usually greetings entering the system and prompts for system operation methods. Synthetic speech is used to broadcast texts whose content changes frequentl...
