C # Baidu Speech synthesis

Speech synthesis and TTS, we try to use the voice synthesis technology of Baidu but I found

One drawback is that there's no offline package that makes me uncomfortable, probably on the online version.

Reason Microsoft speech recognition technology in Windows 2000 is the default integration in system components

Maybe we don't have to look for a new speech synthesis alternative, but once the online version is offline

Only game Over,hah But one advantage is that it is easy to use for GF development

The audio stream after the No. 200-degree speech synthesis, the sister's voice sounds more comfortable if you can

To the "Kawaii" sister, will be better, but should be in the resolution of the sound

The hard feeling might be better, though speech synthesis technology has developed for so many years at least presently I

Have not yet seen what services can provide a natural sense of speaking with people, there will always be some machine

Mechanical but to talk about "Baidu speech recognition" and "optical recognition/OCR" words, I do not well-intentioned

But support the domestic heart is unchanged, but Baidu's documents are only so concise

I can conclude that it must be Baidu's developers, Hah we are not Japanese and

The Indians can't write any notes or documents, they are writing compositions can we build them?

First you need to have a Baidu account, and then to the new version of the official Baidu Voice homepage

Http://yuyin.baidu.com/fc.html

Then you will see the two different technologies above, and we choose speech synthesis technology

You can try a quick experience, which is actually implemented using the rest API, and don't tangle

We click on the use immediately, if it is the first time to use the technical services of Baidu then you need

Register the developer information once the rotten fill best lest Baidu put your information where to sell, Hah.

If you have registered your information, you will not be able to use Baidu services without creating an app.

You must create a project to "Create a new app" in the upper-right corner as shown

Then you will see the following page, feel free to fill out a valid name confirmation can apply the category

is also arbitrary choice, make so clear to Baidu what to do just use service is not sell information

When the app is created you will see the following page, then you need to click the Open service

If you do not see the service tag button, you can return to the Baidu Voice support home page

Select "Baidu Speech Synthesis" and click "Use Now"

It will prompt you to select your app and choose a sucks, then click Next

If the following page indicates success, you can also click "Create App" on the right.

Hyperlink Quick Launch Service

Well, if there is a need for Baidu help document can go to "Application Management" page click on you need

To the technical button, the following shortcut menu will pop up to select "Download SDK", or

From Baidu Voice Support home page Select "Baidu Speech Synthesis"

After clicking "Related Downloads" in the toolbar, we select the "REST API" tab, please refer to

Click Download document, but Baidu's documentation you may have seen that you might think you have not seen Hah.

Now we need to go to "get access Token" is a new thing Baidu got out

We need to go to the "app management" page and click on the "Baidu Voice recognition" technology

App, click on the "View Key" graphic button and it will appear as shown in the

We now need to extract two important parameters and API key, Secret key session

To say why it's called "secret key." I reckoned a thing that's like a cipher.

We stitch a connection to a document to query our own "Access Token".

Https://openapi.baidu.com/oauth/2.0/token?

grant_type=client_credentials&

client_id=hinqtsu6g8c6xqwfvfbwt7tm&

Client_secret=8d5dbdb1b92bf945dca42f75c9eb1a69

Explain:

Grant_type//Authorization type

client_id//API Key

Client_secret//Secret Key

Accessing the above connection in the Browse will see the text JSON code like

What we just need "access_token/access tokens" in something else straight

There is nothing too much to delete and delete.

The following began to write in C # using the Baidu Speech Synthesis Service code, first we

Need to know, Baidu speech synthesis after the output of the audio stream is MP3 not wav

In order for us to play the audio stream we need to ask for media that supports MP3 audio format

Library, but we're simply playing with its audio instead of having to make a music broadcast

The use of MCI is the most convenient and memory-saving approach

From the code above you may be wondering why or there are so many constants then you see

You will know that some friends who watch the document do not

Are you finding the same as the above constants now? It is "Baidu speech synthesis" needs

Some of the "necessary or optional" parameters, the way we use post here is mainly

Is that I'm a little too dick to use get way, although the document is get way

. NET post is not the way it is, generally the most commonly used or

. NET upper layer provides HttpWebRequest, but Baidu speech recognition

Required to use UTF-8 string post, be sure to pay attention to the details here

Otherwise you will not be able to use the service provided by Baidu and return the error code to you

Presumably these details as a developer should not be committed

We write the HTTP stream returned after post to the file, but above

I said Baidu is the return of the MP3 stream, then you need to mp3 the side

Write to a file, and if you use a bass, it does not have to play in-memory

Media streaming, but the MCI way is not, if you don't understand the code

and need to use can copy my code but suggest you can read the best

To the end of the basic, the use of Baidu speech synthesis in C # is not

It's so hard for you to imagine, you don't have to tangle with how it's used.
