我正在尝试使用Azure Cognitive Services文本到语音REST API和Powershell处理纯文本文件以创建wav音频文件。我不明白如何执行此操作，而不是直接将内容（特别是在$Content中）添加到脚本以及如何在此过程中使用自定义词典。我删除了部分脚本（auth）以简化。谢谢。

$AudioOutputType='audio-24khz-96kbitrate-mono-mp3'

$XSearchAppID='000000000000000000000'

$XSearchClientID='00000000000000000000000'

$UserAgent='PowerShellTextToSpeechApp'

$Header=@{ `

'Content-Type' = 'application/ssml+xml'; `

'X-Microsoft-OutputFormat' = $AudioOutputType; `

'X-Search-AppId' = $XSearchAppId; `

'X-Search-ClientId' = $XSearchClientId; `

'Authorization' = $AccessToken `

}

$Locale='es-MX'

$ServiceNameMapping='Microsoft Server Speech Text to Speech Voice (es-MX, DaliaNeural)'

$Content='\path\Test.txt'

$Body=''+$Content+''

$Endpoint= 'https://speech.platform.bing.com/synthesize'

$Method='POST'

$ContentType='application/ssml+xml'

$Filename='output.wav'

Invoke-RestMethod -Uri $Endpoint -Method $Method `

-Headers $Headers -ContentType $ContentType `

-Body $Body -UserAgent $UserAgent `

-OutFile $Filename

谢谢大家！
