System.Speech throws \u201cNo voice installed on the system or none available with the current security setting\u201d exception in Windows Service<\/h4>\n

 <\/p>\n

Long time reader, first time poster.\r\nI'm developing a Windows Service in C# .Net 3.5 to perform Text to Speech operations.\r\nI'm using System.Speech (Microsoft Speech API 3.x).\r\nI deployed the service to a Win2008 x64 server and it's now throwing the following exception:\r\nSystem.InvalidOperationException: No voice installed on the system or none available with the current security setting.\r\nat System.Speech.Internal.Synthesis.VoiceSynthesis.Speak(Prompt prompt)\r\nat System.Speech.Synthesis.SpeechSynthesizer.Speak(Prompt prompt)\r\nat System.Speech.Synthesis.SpeechSynthesizer.Speak(String textToSpeak)\r\nThe service is running under a domain account. If I change the service to run under my own personal domain account (which has pretty high privileges), everything works perfectly (so a voice [Anna] is definitely installed). So I'm quite certain it's a security issue.\r\nWhat permissions\/modifications do I need to make to the other domain account to make this work?\r\nAnd it needs to be this specific user because it's used for Windows auth for a MSSQL database.\r\nThanks in advance.\r\n<\/pre>\n<\/div>\n
\n
Simple fix: Grant read\/write access to C:\\windows\\system32\\config\\systemprofile\\appdata\\roaming for the same user that the service is running under.\r\n<\/pre>\n<\/div>\n
\n
In x64 OS, this is caused by AnyCPU build configuration. Switch to x86 build configuration and it should work.\r\n<\/pre>\n<\/div>\n
\n
i exited Visual Studio and reopened it after it saved, and the problem was solved.\r\n<\/pre>\n<\/div>\n
\n
Simply, run the app as \"administrator\". ;)\r\n\r\nhttps:\/\/csharp.wekeepcoding.com\/article\/19866074\/System.Speech+throws+%E2%80%9CNo+voice+installed+on+the+system+or+none+available+with+the+current+security+setting%E2%80%9D+exception+in+Windows+Service<\/a><\/pre>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
