In the various embodiments with various modifications of special-purpose.
Embodiment 1
The invention discloses a kind of audio frequency transmission method for meeting shorthand system, system such as Fig. 1 institute is taken down in short-hand in the meeting referred to
Show, terminal is mainly taken down in short-hand by the meeting for including conference audio, the ASR server that speech-recognition services are provided, provides natural language
It handles the NLP server of service, the collaborative editing server of back-office support and the human-edited for correcting minutes is provided
Terminal is constituted, and the meeting shorthand terminal is respectively at the ASR server, the NLP server, the collaborative editing server
It is bi-directionally connected, the collaborative editing server is bi-directionally connected with human-edited's terminal.
Meeting shorthand terminal is disposed on meeting scene, is included and pretreated autonomous device to conference audio；People
Work editor terminal is the equipment such as the desktop computer for being mounted with specific software, notebook, and the specific software refers to can be realized it
The software of necessary functions.
Human-edited's terminal and meeting shorthand terminal can be located at different location, such as meeting in Beijing,
Record personnel carry out the amendment of minutes in Shanghai.
Meeting shorthand terminal, ASR server, NLP server, the connection type between human-edited's terminal can use but
It is not limited to cable network, WiFi network, 4G network.
Audio frequency transmission method disclosed in the present embodiment is to take down in short-hand terminal when meeting is carried out by meeting and include conference audio
And audio stream is cut and numbered according to natural sentences, the time interval cut between audio section is 0.00001ms, then will be cut
Audio section after cutting is respectively sent to ASR server and collaborative editing server；Meeting takes down in short-hand terminal when cutting audio stream, right
At the beginning of each audio section, end time, Audiocode recorded and generate journal file；Meeting takes down in short-hand terminal for day
One of will file or a variety of audio feature informations connection audio section are sent to ASR server together.
Here ASR server and NLP server is existing third-party server.ASR server will be in audio section
Appearance is converted into a text, is mechanical conversion in this conversion process, wherein that there are wrong words quite a lot is (mostly same
Sound character error)；NLP server is automatically corrected a text according to natural language, this conversion process is namely based on people
The habit of natural language carries out the process of automatic error-correcting to a text.NLP server is back to the two of meeting shorthand terminal
Secondary text, accuracy is up to 90-95%, but there are still certain error rates.
Here collaborative editing server is for corresponding audio section and secondary text according to journal file.
Audio stream is cut according to natural sentences, this is one of main points of the present embodiment.
People has pause when normally speaking, and the natural sentences in the present embodiment refer to this sentence between adjacent pause
Words, such as " thick mad sound my that the Yellow River " in Fig. 2, " not only ringing in the mansion of the United Nations ".It is carried out according to natural sentences
Audio stream cutting, first is that with can guaranteeing audio-frequency information integrality, the case where preventing audio data from losing；Second is that reducing sound
The bandwidth occupied in frequency transmission process quickly reaches speech text change server convenient for audio, reduces because network traffic congestion causes
Audio is jammed in the road for being sent to speech text change server, this like on the road of a congestion, bicycle,
Battery truck, especially pedestrian can shuttle from automobile gap, and network transmission is similarly.
It fluctuates when detecting in a period of time without audio, just audio stream is cut, it is then subsequent in 0.00001ms
It is continuous to start to process.It will be set to 0.00001ms between audio section, is loss and mistake in order to reduce audio as far as possible
Position.For example, be averaged if being divided into 0.1ms between audio section comprising an audio section interval among 5s audio, 1h audio meeting
72ms deviation is generated, the deviation that 4h audio generates reaches 288ms；If being divided into 0.00001ms between audio section, it is averaged, 1h sound
Frequency only generates 0.0072ms deviation, and the deviation that 4h audio generates is also only 0.0288ms.
If all not detecting pause prolonged enough in 60s, audio stream is cut by force, is avoided
Audio section is too long, influences the transmission speed of audio section and the response speed of ASR server and NLP server.
When audio stream is cut to form audio section, it is with the audio stream that is generating with regard to independent, it is meant that this section
The end of audio, this section audio can be played back by also implying that, convenient for being modified to its corresponding text.
One of journal file or a variety of audio feature informations connection audio section are sent to ASR server together, this
It is the two of the main points of the present embodiment.
At the beginning of audio section, the end time is subject to Beijing time.At the beginning of audio section, the end time,
And its corresponding Audiocode is the information that meeting shorthand terminal can obtain in audio cutting process, but audio section pair
The text answered is the secondary text that NLP server returns.
Ideally, a segment of audio corresponds to passage, carries out corresponding in sequence, but there may be one section
Audio does not correspond to a possibility that text, such as situations such as live play song.What this related to how to return to NLP server
The problem of secondary text and audio section correspond.In the present embodiment, solution to this problem is, if audio section not with
Corresponding text, meeting shorthand terminal is marked in journal file, and collaborative editing server is according to journal file by sound
Frequency range and secondary text are corresponded, if encountering some audio section has label, are just skipped, in order to avoid there is text
The problem of mistake corresponding with audio section occurs.How meeting shorthand terminal knows which section audio section does not have corresponding text, this
It is the data judgement returned by ASR server, such as time started, end time, audio is numbered into one such information
Or much information carries out fusion and forms characteristic information connection audio section sending jointly to ASR server, ASR server, which returns, to be carried
Text of this feature information, meeting shorthand terminal can know that this audio section is sended over either with or without corresponding text.
Audio section is numbered, this is the third key point of the present embodiment.
In the transmission process of audio section and text, audio section is big and text is small, therefore text is often earlier than audio section
Ground is transferred to collaborative editing server, i.e., simultaneously nonsimultaneous transmission takes to collaborative editing server, collaborative editing for audio section and text
How business device knows which section text will be corresponding to which section audio.In the present embodiment, terminal is taken down in short-hand to each section by meeting
Audio and text are numbered to solve the problems, such as this.
Since meeting shorthand terminal, ASR server, NLP server, collaborative editing server, human-edited's terminal are all
By network connection, during meeting carries out, it may occur however that the case where network interruption.When meeting shorthand terminal detects in network
When disconnected, stop sending data to ASR server/NLP server, and data are temporarily deposited in memory, when network connects again
When connecing, data are orderly sent to ASR server/NLP server by memory, after avoiding network reconnection, ASR server/NLP
Server centered receives audio data, is mistakenly considered by attack, and closes meeting shorthand terminal and the connection between it.For
Prevent offline condition occur between meeting shorthand terminal and collaborative editing server, collaborative editing server memory has the meeting of backup
Discuss audio.The conference audio of backup can be used for after the conference is over, and human-edited's terminal transfers conference audio to minutes again
It is modified, rather than minutes must be modified in conference process；It is also possible to prevent meeting from taking down in short-hand terminal
There is the problem of when transmitting obstacle, human-edited's terminal can not obtain audio-frequency information generation between collaborative editing server.
There is offline condition, collaborative editing server memory to prevent meeting from taking down in short-hand between terminal and collaborative editing server
There is the conference audio of backup.The conference audio of backup can be used for after the conference is over, and human-edited's terminal transfers conference audio again
Minutes are modified, rather than minutes must be modified in conference process；It is also possible to prevent meeting
When there is transmission obstacle between view shorthand terminal and collaborative editing server, human-edited's terminal can not obtain asking for audio-frequency information
Topic occurs.
Obviously, described embodiment is only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, this field and those of ordinary skill in the related art institute without creative labor
