Instance Method Details

#delete_lexicon(params = {}) ⇒ Struct

Deletes the specified pronunciation lexicon stored in an AWS Region. A lexicon which has been deleted is not available for speech synthesis, nor is it possible to retrieve it using either the GetLexicon or ListLexicon APIs.

For more information, see Managing Lexicons.

Examples:

Example: To delete a lexicon


# Deletes a specified pronunciation lexicon stored in an AWS Region.

resp = client.delete_lexicon({
  name: "example", 
})

resp.to_h outputs the following:
{
}

Request syntax with placeholder values


resp = client.delete_lexicon({
  name: "LexiconName", # required
})

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :name (required, String) —

    The name of the lexicon to delete. Must be an existing lexicon in the region.

Returns:

  • (Struct) —

    Returns an empty response.

#describe_voices(params = {}) ⇒ Types::DescribeVoicesOutput

Returns the list of voices that are available for use when requesting speech synthesis. Each voice speaks a specified language, is either male or female, and is identified by an ID, which is the ASCII version of the voice name.

When synthesizing speech ( SynthesizeSpeech ), you provide the voice ID for the voice you want from the list of voices returned by DescribeVoices.

For example, you want your news reader application to read news in a specific language, but giving a user the option to choose the voice. Using the DescribeVoices operation you can provide the user with a list of available voices to select from.

You can optionally specify a language code to filter the available voices. For example, if you specify en-US, the operation returns a list of all available US English voices.

This operation requires permissions to perform the polly:DescribeVoices action.

Examples:

Example: To describe available voices


# Returns the list of voices that are available for use when requesting speech synthesis. Displayed languages are those
# within the specified language code. If no language code is specified, voices for all available languages are displayed.

resp = client.describe_voices({
  language_code: "en-GB", 
})

resp.to_h outputs the following:
{
  voices: [
    {
      gender: "Female", 
      id: "Emma", 
      language_code: "en-GB", 
      language_name: "British English", 
      name: "Emma", 
    }, 
    {
      gender: "Male", 
      id: "Brian", 
      language_code: "en-GB", 
      language_name: "British English",

#put_lexicon(params = {}) ⇒ Struct

Stores a pronunciation lexicon in an AWS Region. If a lexicon with the same name already exists in the region, it is overwritten by the new lexicon. Lexicon operations have eventual consistency, therefore, it might take some time before the lexicon is available to the SynthesizeSpeech operation.

For more information, see Managing Lexicons.

Examples:

Example: To save a lexicon


# Stores a pronunciation lexicon in an AWS Region.

resp = client.put_lexicon({
  content: "file://example.pls", 
  name: "W3C", 
})

resp.to_h outputs the following:
{
}

Request syntax with placeholder values


resp = client.put_lexicon({
  name: "LexiconName", # required
  content: "LexiconContent", # required
})

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :name (required, String) —

    Name of the lexicon. The name must follow the regular express format [0-9A-Za-z]{1,20\}. That is, the name is a case-sensitive alphanumeric string up to 20 characters long.

  • :content (required, String) —

    Content of the PLS lexicon as string data.

Returns:

  • (Struct) —

    Returns an empty response.

#start_speech_synthesis_task(params = {}) ⇒ Types::StartSpeechSynthesisTaskOutput

Allows the creation of an asynchronous synthesis task, by starting a new SpeechSynthesisTask. This operation requires all the standard information needed for speech synthesis, plus the name of an Amazon S3 bucket for the service to store the output of the synthesis task and two optional parameters (OutputS3KeyPrefix and SnsTopicArn). Once the synthesis task is created, this operation will return a SpeechSynthesisTask object, which will include an identifier of this task as well as the current status.

Examples:

  • :speech_mark_types (Array<String>) —

    The type of speech marks returned for the input text.

  • :text (required, String) —

    The input text to synthesize. If you specify ssml as the TextType, follow the SSML format for the input text.

  • :text_type (String) —

    Specifies whether the input text is plain text or SSML. The default value is plain text.

  • :voice_id (required, String) —

    Voice ID to use for the synthesis.

  • :language_code (String) —

    Optional language code for the Speech Synthesis request. This is only necessary if using a bilingual voice, such as Aditi, which can be used for either Indian English (en-IN) or Hindi (hi-IN).

    If a bilingual voice is used and no language code is specified, Amazon Polly will use the default language of the bilingual voice. The default language for any voice is the one returned by the DescribeVoices operation for the LanguageCode parameter. For example, if no language code is specified, Aditi will use Indian English rather than Hindi.

#synthesize_speech(params = {}) ⇒ Types::SynthesizeSpeechOutput

Synthesizes UTF-8 input, plain text or SSML, to a stream of bytes. SSML input must be valid, well-formed SSML. Some alphabets might not be available with all the voices (for example, Cyrillic might not be read at all by English voices) unless phoneme mapping is used. For more information, see How it Works.

Examples:

Example: To synthesize speech


# Synthesizes plain text or SSML into a file of human-like speech.

resp = client.synthesize_speech({
  lexicon_names: [
    "example", 
  ], 
  output_format: "mp3", 
  sample_rate: "8000", 
  text: "All Gaul is divided into three parts", 
  text_type: "text", 
  voice_id: "Joanna", 
})

resp.to_h outputs the following:
{
  audio_stream: "TEXT", 
  content_type: "audio/mpeg", 
  request_characters: 37, 
}

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :lexicon_names (Array<String>) —

    List of one or more pronunciation lexicon names you want the service to apply during synthesis. Lexicons are applied only if the language of the lexicon is the same as the language of the voice. For information about storing lexicons, see PutLexicon.

  • :output_format (required, String) —

    The format in which the returned output will be encoded. For audio stream, this will be mp3, ogg_vorbis, or pcm. For speech marks, this will be json.

    When pcm is used, the content returned is audio/pcm in a signed 16-bit, 1 channel (mono), little-endian format.

  • :sample_rate (String) —

    The audio frequency specified in Hz.

    The valid values for mp3 and ogg_vorbis are "8000", "16000", and "22050". The default value is "22050".

    Valid values for pcm are "8000" and "16000" The default value is "16000".

  • :speech_mark_types (Array<String>) —

    The type of speech marks returned for the input text.

  • :text (required, String) —

    Input text to synthesize. If you specify ssml as the TextType, follow the SSML format for the input text.

  • :text_type (String) —

    Specifies whether the input text is plain text or SSML. The default value is plain text. For more information, see Using SSML.

  • :voice_id (required, String) —

    Voice ID to use for the synthesis. You can get a list of available voice IDs by calling the DescribeVoices operation.

  • :language_code (String) —

    Optional language code for the Synthesize Speech request. This is only necessary if using a bilingual voice, such as Aditi, which can be used for either Indian English (en-IN) or Hindi (hi-IN).

    If a bilingual voice is used and no language code is specified, Amazon Polly will use the default language of the bilingual voice. The default language for any voice is the one returned by the DescribeVoices operation for the LanguageCode parameter. For example, if no language code is specified, Aditi will use Indian English rather than Hindi.
