Batch text to speech error

Question

Hello, i'm trying to use Batch text to speech following this instructions : https://learn.microsoft.com/fr-fr/azure/cognitive-services/speech-service/spx-batch-operations.
But when I try these commands :
spx synthesize --foreach in @C:\speech\test.tsv --voice fr-FR-BrigitteNeural
spx synthesize --foreach in @C:\speech\test.tsv

I get this error :
SPX - Azure Speech CLI, Version 1.24.1
Copyright (c) 2022 Microsoft Corporation. All Rights Reserved.

  diagnostics.config.log.file=log-{run.time}.log  
  foreach.0.tsv.file=@C:\Studio_Lunii\speech\test.tsv  
  foreach.0.tsv.file.has.header=true  
  foreach.count=1  
  service.config.key= d408****************************  
  service.config.region=francecentral  
  x.command=synthesize  
  x.input.path=@none  
  
  ERROR: Object reference not set to an instance of an object.  

These simple commands are working well :

spx synthesize --text "Testing synthesis using the Speech CLI" --speakers  
spx synthesize --text "Bienvenue chez moi." --voice fr-FR-BrigitteNeural --speakers  

C:\speech\test.tsv looks like this :

audio.output text
C:\speech\Output\0.wav Test 1
C:\speech\Output\1.wav Test 2

Answer 1

@EDS Thanks for the question. make sure that your file contains a tab rather than spaces between the file location and the text. Here is the sample test.csv that you can try.

audio. Output text
C:\speech\Output\0.wav Test 1
C:\speech\Output\1.wav Test 2

Answer 2

It fails too when i use the Microsoft sample TSV file (just changed path).

audio.output text
C:\speech\Output\wav_1.wav Sample text to synthesize.
C:\speech\Output\wav_2.wav Using the Speech CLI to run batch-synthesis.
C:\speech\Output\wav_3.wav Some more text to test capabilities.

Here is the exception.133120138775965417.2600.133120138776623192.spx.error.log :

I don't know what the D:\ refers to, I don't have a D: drive on my PC. The error seems to concern "foreach" because this last command works well:

spx synthesize --text "Exemple de texte" --audio output C:\speech\output\wav_1.wav  --voice fr-FR-BrigitteNeural
