Defaults to the `SARVAM_API_KEY` environment variable. Transcription model id. Default `'saaras:v3'`. Spoken language code. Default `'en-IN'`. Sample rate (Hz) of the audio sent in. Default `48000`. Sample rate in Hz that input audio is resampled to. Default `16000`. Decoding mode. Default `null` (provider default). Use a more sensitive VAD profile. Default `null`. Emit flush signals between turns. Default `null`. Translate transcripts to the target language. Default `false`. Optional prompt to bias transcription. Default `null`. Input audio codec. Default `'pcm_s16le'`. Emit VAD signals. Default `true`. VAD probability above which a frame counts as speech. Default `null`. VAD probability below which a frame counts as non-speech. Default `null`. Minimum frames of speech to start a turn. Default `null`. Minimum speech frames for the first turn. Default `null`. Audio frames of padding prepended before speech. Default `null`. Minimum speech frames required to interrupt. Default `null`. ### close ```typescript theme={null} close(): Promise ``` Release any resources held by the provider. ### closeEmitter ```typescript theme={null} closeEmitter(): Promise ``` Close the emitter: drop all handlers and stop emitting. Waits up to 2 seconds for in-flight async handlers to settle before returning. ### emit ```typescript theme={null} emit(event: string, ...args: any[]): void ``` ### getRuntimeConfig ```typescript theme={null} getRuntimeConfig(): Record ``` ### listenerCount ```typescript theme={null} listenerCount(event: string): number ``` ### off ```typescript theme={null} off(event: string, handler: EventHandler): void ``` ### on ```typescript theme={null} on(event: string, handler: EventHandler): EventHandler ``` ### once ```typescript theme={null} once(event: string, handler: EventHandler): EventHandler ``` ### onSttTranscript ```typescript theme={null} onSttTranscript(callback: SttTranscriptCallback): void ``` Register a callback to receive transcripts as they are produced. ### processAudio ```typescript theme={null} processAudio(_audioFrames: Uint8Array, _language?: string | null, ..._extra: any[]): Promise ``` Process a buffer of audio frames. Override in a custom provider. ### removeAllListeners ```typescript theme={null} removeAllListeners(event?: string): void ``` ### streamTranscribe ```typescript theme={null} streamTranscribe(_audioStream: AsyncIterable, ..._extra: any[]): AsyncIterator ``` Transcribe a streaming audio source, yielding STTResponses. Override in a custom provider. *** ## SarvamAISTTModel Supported Sarvam AI STT model names. ### Fields Returns a string representation of a string. Returns the character at the specified index. Returns the Unicode value of the character at the specified location. Returns a string that contains the concatenation of two or more strings. Returns the position of the first occurrence of a substring. Returns the last occurrence of a substring in the string. Determines whether two strings are equivalent in the current locale. Matches a string with a regular expression, and returns an array containing the results of that search. Replaces text in a string, using a regular expression or search string. Finds the first substring match in a regular expression search. Returns a section of a string. Split a string into substrings using the specified separator and return them as an array. Returns the substring at the specified location within a String object. Converts all the alphabetic characters in a string to lowercase. Converts all alphabetic characters to lowercase, taking into account the host environment's current locale. Converts all the alphabetic characters in a string to uppercase. Returns a string where all alphabetic characters have been converted to uppercase, taking into account the host environment's current locale. Removes the leading and trailing white space and line terminator characters from a string. Returns the length of a String object. Gets a substring beginning at the specified location and having the specified length. Returns the primitive value of the specified object. Returns a nonnegative integer Number less than 1114112 (0x110000) that is the code point value of the UTF-16 encoded code point starting at the string element at position pos in the String resulting from converting this object to a String. If there is no element at that position, the result is undefined. If a valid UTF-16 surrogate pair does not begin at pos, the result is the code unit at pos. Returns true if searchString appears as a substring of the result of converting this object to a String, at one or more positions that are greater than or equal to position; otherwise, returns false. Returns true if the sequence of elements of searchString converted to a String is the same as the corresponding elements of this object (converted to a String) starting at endPosition – length(this). Otherwise returns false. Returns the String value result of normalizing the string into the normalization form named by form as specified in Unicode Standard Annex #15, Unicode Normalization Forms. Returns a String value that is made from count copies appended together. If count is 0, the empty string is returned. Returns true if the sequence of elements of searchString converted to a String is the same as the corresponding elements of this object (converted to a String) starting at position. Otherwise returns false. Returns an `` HTML anchor element and sets the name attribute to the text value Returns a `` HTML element Returns a `` HTML element Returns a `` HTML element Returns a `` HTML elementReturns a `` HTML element and sets the color attribute value Returns a `` HTML element and sets the size attribute value Returns an `` HTML element Returns an `` HTML element and sets the href attribute valueReturns a `` HTML element Returns a `` HTML element Returns a `_{` HTML element} Returns a `^{` HTML element} Pads the current string with a given string (possibly repeated) so that the resulting string reaches a given length. The padding is applied from the start (left) of the current string. Pads the current string with a given string (possibly repeated) so that the resulting string reaches a given length. The padding is applied from the end (right) of the current string. Removes the trailing white space and line terminator characters from a string. Removes the leading white space and line terminator characters from a string. Removes the leading white space and line terminator characters from a string. Removes the trailing white space and line terminator characters from a string. Matches a string with a regular expression, and returns an iterable of matches containing the results of that search. Replace all instances of a substring in a string, using a regular expression or search string. Returns a new String consisting of the single UTF-16 code unit located at the specified index.
