New Japanese next-generation telephony model
: The service now offers a next-generation telephony model for Japanese: ja-JP_Telephony. The new model supports low latency and is generally available. It also supports language model customization and grammars. For more information about next-generation models and low latency, see



* [Next-generation languages and models](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-models-ng)
* [Customization support for next-generation models](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-custom-supportcustom-language-support-ng)
* [Low latency](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-interimlow-latency)



Improved language model customization for next-generation English and Japanese models
: The service now provides improved language model customization for next-generation English and Japanese models:



* en-AU_Multimedia
* en-AU_Telephony
* en-IN_Telephony
* en-GB_Multimedia
* en-GB_Telephony
* en-US_Multimedia
* en-US_Telephony
* ja-JP_Multimedia

Visible improvements to the models: The new technology improves the default behavior of the new English and Japanese models. Among other changes, the new technology optimizes the default behavior for the following parameters:



* The default customization_weight for custom models that are based on the new versions of these models changes from 0.2 to 0.1.
What happens when I add a corpus file? 

When you add a corpus file, the service analyzes the file's contents. It extracts any new (OOV) words that it finds and adds each OOV word to the custom model's words resource. To distill the most meaning from the content, the service tokenizes and parses the data that it reads from a corpus file. The following sections describe how the service parses a corpus file for each supported language.



 Parsing of Dutch, English, French, German, Italian, Portuguese, and Spanish 

The following descriptions apply to all supported dialects of Dutch, English, French, German, Italian, Portuguese, and Spanish.



* Converts numbers to their equivalent words.



Table 1. Examples of number conversion

 Language Whole number Decimal number 

 Dutch 500 becomes vijfhonderd 0,15 becomes nul komma vijftien 
 English 500 becomes five hundred 0.15 becomes zero point fifteen 
 French 500 becomes cinq cents 0,15 becomes zéro virgule quinze 
 German 500 becomes fünfhundert 0,15 becomes null punkt fünfzehn 
 Italian 500 becomes cinquecento 0,15 becomes zero virgola quindici 
 Portuguese 500 becomes quinhentos 0,15 becomes zero ponto quinze 
 Spanish 500 becomes quinientos 0,15 becomes cero coma quince 



* Converts tokens that include certain symbols to meaningful string representations. These examples are not exhaustive. The service makes similar adjustments for other characters as needed. (For Spanish, if the dialect is es-LA, $100 and 100$ become cien pesos.)



Table 2. Examples of symbol conversion

 Language A dollar sign and a number A euro sign and a number A percent sign and a number 

 Dutch $100 becomes honderd dollar €100 becomes honderd euro 100% becomes honderd procent 
 English $100 becomes one hundred dollars €100 becomes one hundred euros 100% becomes one hundred percent 
 French $100 becomes cent dollars €100 becomes cent euros 100% becomes cent pour cent 
 German $100 and 100$ become einhundert dollar €100 and 100€ become einhundert euro 100% becomes einhundert prozent

Updates to import/export scripts
: The import_export.sh and transfer_ownership.sh scripts have been updated. These scripts are used to import and export data between clusters, back up and restore data, and migrate data from version 3.5 to version 4.0.x. The scripts have been modified and improved as follows:



* The transfer_ownership.sh script now requires a -c option to be included on the command line before the <custom_resource_name> argument.
* The transfer_ownership.sh script now requires a -v <version> option and argument to indicate the version to which ownership of resources is being transferred. Specify 35 for version 3.5 or 40 for version 4.0.x.
* The transfer_ownership.sh script now requires a -p option to be included on the command line before the <postgres_auth_secret_name> argument.
* The <postgres_auth_secret_name> argument provides the Kubernetes secret that is used to authenticate to the PostgreSQL datastore to which you are transferring ownership. You can omit the authentication secret if is the same as the default value (<custom-resource-name>-postgres-auth-secret for version 4.0.x, user-provided-postgressql for version 3.5).
: The following next-generation models have been updated for improved speech recognition. All of the models are generally available.



* Arabic: ar-MS_Telephony. The model now supports low latency.
* Brazilian Portuguese: pt-BR_Telephony. The model continues to support low latency.
* US English: en-US_Telephony. The model continues to support low latency.
* Canadian French: fr-CA_Telephony. The model now supports low latency.
* Italian: it-IT_Telephony. The model now supports low latency.



For more information about all next-generation models and about low latency, see [Next-generation languages and models](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-models-ng) and [Low latency](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-interimlow-latency).

Defect fix: Address asynchronous HTTP failures
: Defect fix: The asynchronous HTTP interface failed to transcribe some audio. In addition, the callback for the request returned status recognitions.completed_with_results instead of recognitions.failed. This error has been resolved.

Defect fix: Improve speakers labels results
: Defect fix: When you use speakers labels with next-generation models, the service now identifies the speaker for all words of the input audio, including very short words that have the same start and end timestamps.

Defect fix: Update interim results and low-latency documentation
: Defect fix: Documentation that describes the interim results and low-latency features with next-generation models has been rewritten for clarity and correctness. For more information, see the following topics:
* [Customization support for next-generation models](https://cloud.ibm.com/docs/speech-to-text?topic=speech-to-text-custom-supportcustom-language-support-ng)
