按照Creating Voice Audio Files的文档以及Google Cloud Platform的 Text-to-Speech API，使用Speech Synthesis Markup Language (SSML)时发生以下错误，而使用相同格式的内容时则没有错误作为标准文字。
这是使用 SSML 时出现的错误，由于 SSML 的字符数远低于 5000 限制，因此似乎不准确在 2979 ：
错误：3个INVALID_ARGUMENT：超过5000个字符的限制。
const Speech = require('ssml-builder');
const textToSpeech = require('@google-cloud/text-to-speech');
...
const client = new textToSpeech.TextToSpeechClient();
const speech = new Speech();
...
console.log('Convert Article ' + data.id + ': ' + data.text);
return client.synthesizeSpeech({
input: { text: data.text},
voice: {
languageCode: '[language-code]',
name: '[language-option]',
},
audioConfig: {
audioEncoding: '[encoding-type]',
pitch: "[pitch]",
speakingRate: "[speaking-rate]"
},
})
使用ssml-builder软件包。
console.log('Convert Article ' + data.id + ': ' + speech.say(data.text).ssml());
return client.synthesizeSpeech({
input: { ssml: speech.say(data.text).ssml()},
voice: {
languageCode: '[language-code]',
name: '[language-option]',
},
audioConfig: {
audioEncoding: '[encoding-type]',
pitch: "[pitch]",
speakingRate: "[speaking-rate]"
},
})
文章：Reports Of Bitcoin's Demise Have Been 'Greatly Exaggerated'
字符数：2904
The current bitcoin bear market, labeled crypto winter for its debilitating effect on the broader market and industry, has seen more than $700 billion wiped from the total value of all cryptocurrencies so far this year, some 80% of its value since its all-time high.
Bitcoin has seen similar price percentage declines before, however, and has managed to recover from them. Now, researchers from the University of Cambridge Judge Business School have found the bitcoin industry will "likely" bounce back again.
"Statements proclaiming the death of the crypto-asset industry have been made after every global ecosystem bubble," researchers wrote in the second Global Cryptoasset Benchmarking Study. "While it is true that the 2017 bubble was the largest in bitcoin's history, the market capitalization of both bitcoin and the crypto-asset ecosystem still exceeds its January 2017 levels-prior to the start of the bubble.
"The speculation of the death of the market and ecosystem has been greatly exaggerated, and so it seems likely that the future expansion plans of industry participants will, at most, be delayed."
While the bitcoin industry still has many supporters despite the price collapse, others have been quick to brand bitcoin as dead, something that's happened more than 300 times according to the loosely-updated tracking website 99bitcoins.
Elsewhere, bitcoin bulls, such former Goldman Sachs partner and founder of cryptocurrency merchant bank Galaxy Digital Holdings Mike Novogratz, have sobered up since the giddy highs of late 2017.
Researchers also found that millions of new users have entered the ecosystem over the last 12 months, though most are passive -- buying bitcoin or other cryptocurrencies with newly created wallets and then not moving or using them.
Total user accounts at service providers now exceed 139 million with at least 35 million identity-verified users, the latter growing nearly four-fold in 2017 and doubling again in the first three quarters of 2018, according to the report.
Only 38% of all users can be considered active, although definitions and criteria of activity levels vary significantly across service providers.
Meanwhile, the study found that the top six proof-of-work cryptocurrencies (including bitcoin and ethereum) collectively consume between 52 TWh and 111 TWh of electricity per year: the mid-point of the estimate (82 TWh) is the equivalent of the total energy consumed by the entire country of Belgium -- but also constitutes less than 0.01% of the world's global energy production per year.
A "notable" share of the energy consumed by these facilities is supplied by renewable energy sources in regions with excess capacity, the researchers revealed.
The report also found that cryptocurrency mining appears to be less concentrated geographically, in hashing power ownership, and in manufacturer options, than is widely thought.

答案 0 :(得分：0)
即：
console.log('Convert Article ' + data.id + ': ' + (new Speech()).say(data.text).ssml())
Speech对象创建一次，但是使用了两次。创建后，它既可以用于记录文本内容以进行调试（具有讽刺意味的是， ），又可以用于写入导致达到配额的文件。
const speech = new Speech();
console.log('Convert Article ' + data.id + ': ' + speech.say(data.text).ssml())
input: { ssml: speech.say(data.text).ssml()}
