HTTP Mapping: PATCH /v1/conversation/speech/\{speech.name=speeches/\*} Reference: https://docs.machanirobotics.dev/v-2026-01-16-dev/2026-01-16-dev/latest/speech-service/updatespeech ## Request ### Path parameters - `speeche` (string, required) — The speeche id. ### Query parameters - `updateMask` (string, optional) — update_mask specifies the set of fields to be updated in the Speech resource. This enables partial updates by listing only the modified field paths. ### Body (application/json) This endpoint expects a Speech. - `displayName` (string, required) — display name contains the display name for the relevant speech. - `content` (string, required) — content contains the actual textual content to be converted into speech. This field is required to generate the speech output. - `service` (integer, required) — service specifies the speech processing service to use for generating the speech. It must be one of the defined values in the SpeechProcessingService enum. - `languageTag` (InferenceLanguage, required) — language specifies the language of the speech content. - `name` (string, optional) — name is the resource identifier for the Speech. It follows the format "speeches/\{speech}" and uniquely identifies a Speech resource. - `speed` (double, optional) — speed defines the playback speed of the generated speech. This optional field allows for customization of the speech delivery rate. - `outputFormat` (integer, optional) — output_format determines the file format for the synthesized speech audio, such as MP3 or WAV. This field is optional and depends on the capabilities of the selected service. - `duration` (string, optional) — duration specifies the maximum length of the speech output in seconds. This field is required to limit the length of the generated speech. - `audioUri` (string, optional) — Storage URI for the synthesized speech audio. This field is optional and depends on the capabilities of the selected service. - `type` (integer, optional) — type specifies the storage behavior of the speech output. It indicates whether the generated speech should be persisted for future reference or treated as transient. ## Response ### 200 OK - `displayName` (string, required) — display name contains the display name for the relevant speech. - `content` (string, required) — content contains the actual textual content to be converted into speech. This field is required to generate the speech output. - `service` (integer, required) — service specifies the speech processing service to use for generating the speech. It must be one of the defined values in the SpeechProcessingService enum. - `languageTag` (InferenceLanguage, required) — language specifies the language of the speech content. - `name` (string, optional) — name is the resource identifier for the Speech. It follows the format "speeches/\{speech}" and uniquely identifies a Speech resource. - `speed` (double, optional) — speed defines the playback speed of the generated speech. This optional field allows for customization of the speech delivery rate. - `outputFormat` (integer, optional) — output_format determines the file format for the synthesized speech audio, such as MP3 or WAV. This field is optional and depends on the capabilities of the selected service. - `duration` (string, optional) — duration specifies the maximum length of the speech output in seconds. This field is required to limit the length of the generated speech. - `audioUri` (string, optional) — Storage URI for the synthesized speech audio. This field is optional and depends on the capabilities of the selected service. - `type` (integer, optional) — type specifies the storage behavior of the speech output. It indicates whether the generated speech should be persisted for future reference or treated as transient. ## Errors ### 400 Bad Request Error Bad Request - `code` (integer, optional) — The status code, which should be an enum value of [google.rpc.Code][google.rpc.Code]. - `message` (string, optional) — A developer-facing error message, which should be in English. Any user-facing error message should be localized and sent in the [google.rpc.Status.details][google.rpc.Status.details] field, or localized by the client. - `details` (list of GoogleProtobufAny, optional) — A list of messages that carry the error details. There is a common set of message types for APIs to use. ## Types ### InferenceLanguage InferenceLanguage is the language code for the robot's conversation. - `countryTag` (integer, required) — The country code for the robot's conversation. - `languageTag` (integer, required) — The language code for the robot's conversation. - `inputAudio` (string, optional) — The audio input for the robot's conversation. - `inputText` (string, optional) — The text input for the robot's conversation. - `inputSpeech` (string, optional) — The speech input for the robot's conversation. - `inputNone` (boolean, optional) — The none input for the robot's conversation. - `outputAudio` (string, optional) — The audio output for the robot's conversation. - `outputText` (string, optional) — The text output for the robot's conversation. - `outputSpeech` (string, optional) — The speech output for the robot's conversation. - `outputNone` (boolean, optional) — The none output for the robot's conversation. ### GoogleProtobufAny Contains an arbitrary serialized message along with a @type that describes the type of the serialized message. - `@type` (string, optional) — The type of the serialized message. ## Examples **Request** ```json { "displayName": "Welcome Greeting", "content": "Hello, welcome to Machani Robotics.
