text: Title: [Bug] Bark Model can not generate special sounds
  Body: ### Describe the bug
  
   I have encountered an issue where the output I receive differs from the output shown in the official repository, even though I am using the same prompt that is provided. This discrepancy is creating confusion and making it difficult for me to understand and compare my results with the expected outcomes.
  my code
  ```
  from TTS.api import TTS
  import time
  
  # Load the model to GPU
  # Bark is really slow on CPU, so we recommend using GPU.
  tts = TTS("tts_models/multilingual/multi-dataset/bark", gpu=True)
  
  
  text = """
      ♪ In the jungle, the mighty jungle, the lion barks tonight ♪
      """
  tts.tts_to_file(text=text,
                  file_path="output.wav",
                  voice_dir="bark-voices/",
                  speaker="en_speaker_9")
  ```
  bark example code
  ```
  from bark import SAMPLE_RATE, generate_audio, preload_models
  from scipy.io.wavfile import write as write_wav
  from IPython.display import Audio
  
  # download and load all models
  preload_models()
  
  # generate audio from text
  text_prompt = """
      ♪ In the jungle, the mighty jungle, the lion barks tonight ♪
  """
  audio_array = generate_audio(text_prompt)
  
  # save audio to disk
  write_wav("bark_generation.wav", SAMPLE_RATE, audio_array)
    
  # play text in notebook
  Audio(audio_array, rate=SAMPLE_RATE)
  
  ```
  
  TTS can not generate the song
  
  ### To Reproduce
  
  python code
  ```
  from TTS.api import TTS
  import time
  
  # Load the model to GPU
  # Bark is really slow on CPU, so we recommend using GPU.
  tts = TTS("tts_models/multilingual/multi-dataset/bark", gpu=True)
  
  
  text = """
      ♪ In the jungle, the mighty jungle, the lion barks tonight ♪
      """
  tts.tts_to_file(text=text,
                  file_path="output.wav",
                  voice_dir="bark-voices/",
                  speaker="en_speaker_9")
  ```
  
  ### Expected behavior
  
  generate the song
