Problems solved by technology

However, in the process of recording, some unimportant content is often recorded together. When the existing method plays the recording, the user often needs to manually switch to fast-forward playback, or directly skip unimportant content.
Especially when the recording environment is not good, the quality of the recorded voice data is often poor. In order to hear the recording content clearly, the user needs to manually repeat the playback many times, which greatly reduces the user experience.

Embodiment Construction

[0086] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0087] Such as figure 1 Shown, is the flow chart of the voice playing method of the embodiment of the present invention, comprises the following steps:

[0088] Step 101, receiving voice data to be played.

[0089] The voice data may be TV program recordings, interview recordings, meeting recordings, and the like.

[0090] Step 102, performing endpoint detection on the voice data to be played to obtain each voice segment.

[0091] The endpoint detection can adopt some existing detection technologies, such as endpoint detection based on short-term energy and short-term average zero-crossing rate, endpoint detection based on cepstrum feature, endpoint detection based on entropy, and the like.

[0092] Step 103,...

Abstract

The invention discloses a voice playing method and device. The method comprises the steps that voice data to be played are received; endpoint detection is performed on the voice data to be played so that all voice segments are obtained; whether all the voice is key information segments is determined; and voice speed of the voice data to be played is adjusted according to the key information segments when the voice data to be played are played. With application of the voice playing method and device, users can be assisted to rapidly and accurately find the focused voice segments.

Description

technical field [0001] The invention relates to the field of voice signal processing, in particular to a voice playing method and device. Background technique [0002] At present, more and more people like to record the information they need in the form of audio recording instead of text. For example, when a meeting is held, the content of the meeting is recorded in the form of audio recording for subsequent reference; Record it in the form of recording, and edit it into a manuscript based on the content; when students are in class, they record the parts they don't understand, and go back to check the information. However, when the amount of recording data is large, it is difficult for people to quickly and accurately find valuable recording content. In order to reduce the playback time of the recording, the existing voice playback method generally adopts the method of endpoint detection to detect pure noise segments or silent segments, skip these voice segments, and play t...
