Problem With Speech Synthesis.

by ADMIN 31 views

Introduction

Speech synthesis is a powerful tool that allows us to convert text into spoken words. However, when using the UnrealSpeech API, we may encounter issues with speech synthesis. In this article, we will explore the problem of speech synthesis and provide a solution to overcome the limitations of the API.

Understanding the Error

When trying to use a voice other than the ones provided by the UnrealSpeech API, we encounter an error. The error message indicates that there is a bad request for the URL https://api.v6.unrealspeech.com/synthesisTasks. This suggests that the API is not able to process the request due to an invalid voice ID.

Code Analysis

Let's take a closer look at the code provided:

from unrealspeech import UnrealSpeechAPI, play, save

api_key = 'My key here'
speech_api = UnrealSpeechAPI(api_key)

# Create a synthesis task
task_id = speech_api.create_synthesis_task(text=Content, voice_id="af_sarah", bitrate="320k", timestamp_type="word", speed=0, pitch=1.0)

# Check the task status
audio_data = speech_api.get_synthesis_task_status(task_id)

# Play audio
play(audio_data)

save(audio_data, "output.mp3")

The code creates a synthesis task using the create_synthesis_task method of the UnrealSpeechAPI class. However, the voice ID used is "af_sarah", which is not one of the provided voices.

Solution

To overcome the limitation of the API, we need to use one of the provided voices. The available voices are:

  • Scarlett
  • Liv
  • Dan
  • Will
  • Amy

We can modify the code to use one of these voices. For example, let's use the voice "Scarlett":

from unrealspeech import UnrealSpeechAPI, play, save

api_key = 'My key here'
speech_api = UnrealSpeechAPI(api_key)

# Create a synthesis task
task_id = speech_api.create_synthesis_task(text=Content, voice_id="Scarlett", bitrate="320k", timestamp_type="word", speed=0, pitch=1.0)

# Check the task status
audio_data = speech_api.get_synthesis_task_status(task_id)

# Play audio
play(audio_data)

save(audio_data, "output.mp3")

GitHub and API Keys

As a first-time GitHub user, you may be wondering how to handle API keys. API keys are used to authenticate requests to the UnrealSpeech API. To use the API, you need to create an account on the UnrealSpeech website and obtain an API key.

When using the API, you should keep your API key secure and not share it with anyone. You can store your API key in a secure location, such as an environment variable or a secrets manager.

Conclusion

In this article, we explored the problem of speech synthesis using the UnrealSpeech API. We analyzed the error message and identified the cause of the issue. We then provided a solution to overcome the limitation of the API by using one of the provided voices.

We also discussed how to handle API keys and store them securely. By following the steps outlined in this article, you should be able to overcome the problem of speech synthesis and use the UnrealSpeech API to convert text into spoken words.

Troubleshooting

If you encounter any issues with the UnrealSpeech API, you can try the following troubleshooting steps:

  • Check the API key and ensure it is correct.
  • Verify that the voice ID is one of the available voices.
  • Check the bitrate and timestamp type parameters.
  • Check the speed and pitch parameters.

By following these troubleshooting steps, you should be able to resolve any issues with the UnrealSpeech API.

Code Snippets

Here are some code snippets that demonstrate how to use the UnrealSpeech API:

from unrealspeech import UnrealSpeechAPI, play, save

api_key = 'My key here'
speech_api = UnrealSpeechAPI(api_key)

# Create a synthesis task
task_id = speech_api.create_synthesis_task(text="Hello, world!", voice_id="Scarlett", bitrate="320k", timestamp_type="word", speed=0, pitch=1.0)

# Check the task status
audio_data = speech_api.get_synthesis_task_status(task_id)

# Play audio
play(audio_data)

save(audio_data, "output.mp3")

from unrealspeech import UnrealSpeechAPI, play, save

api_key = 'My key here'
speech_api = UnrealSpeechAPI(api_key)

# Create a synthesis task
task_id = speech_api.create_synthesis_task(text="This is a test.", voice_id="Liv", bitrate="320k", timestamp_type="word", speed=0, pitch=1.0)

# Check the task status
audio_data = speech_api.get_synthesis_task_status(task_id)

# Play audio
play(audio_data)

save(audio_data, "output.mp3")
