Configuration Parameters

configuration parameters allow you to customize and personalize your digital human's behavior, appearance, and functionality these attributes are available across all digital human creation methods and can be modified after initial setup to refine the end user experience most parameters can be updated at any time using the docid\ gjy qc6alw5tk6sscxrpp endpoint multiple parameters can be changed in a single update request we distinguish between streaming digital humans (default) and legacy synthesizer digital humans (higher latency) some parameters such as text splitter or ttsstream need to be set accordingly for embedding of the streaming digital humans, please refer to https //docs unith ai/embedding streaming digital humans default conversation parameters greetings this is the welcome message that the digital human will deliver to the end user upon first interaction type string example \["hi there, i am john"] operating modes applies to all curl x 'put' \\ 'https //platform api unith ai/head/update' \\ h 'accept application/json' \\ h 'authorization bearer yourbearertoken' \\ h 'content type application/json' \\ d '{ "id" "yourheadid", "greetings" "hi there, i am john how can i help you today?" }' suggestions these are a list of menu like options that suggest to the user what to engage the digital human about these options are clickable via the unith front end type list of strings example \["who is unith", "where are unith offices?"] operating modes doc qa, oc curl x 'put' \\ 'https //platform api unith ai/head/update' \\ h 'accept application/json' \\ h 'authorization bearer yourbearertoken' \\ h 'content type application/json' \\ d '{ "id" "yourheadid", "suggestions" \[ "who is unith?", "where are unith offices located?", "tell me about your services" ] }' in doc qa mode, suggestions are automatically generated when you upload a document review and edit these suggestions to match your use case each new document upload overwrites the existing suggestions list, so keep a local backup before uploading new documents suggestions can only be clicked once per conversational session after a user selects a suggestion, it becomes unavailable for the remainder of that session israndomsuggestions controls whether suggestions are displayed in random order or in the sequence defined in your suggestions list type true/false values true (random order) or false (sequential order) operating modes doc qa, oc curl x 'put' \\ 'https //platform api unith ai/head/update' \\ h 'accept application/json' \\ h 'authorization bearer

your use case needs semanticthreshold controls the semantic similarity threshold for retrieving cached responses in conversations for detailed information on semantic caching and performance optimization, check out the documentation https //docs unith ai/semantic cache for digital human responses videocache enables or disables video response caching when enabled, generated video responses are stored and reused for identical or semantically similar queries type boolean default true operating modes all modes curl x 'put' \\ 'https //platform api unith ai/head/update' \\ h 'accept

response times for frequently asked questions this works in conjunction with semanticthreshold settings ttsstream controls whether text to speech audio is streamed in real time or pre generated before delivery type boolean default false values true audio is streamed as it's generated (lower latency for first audio) false audio is fully generated before delivery (more stable playback) operating modes all modes when using streaming mode you need to use a provider that supports audio streaming ttsstream text splitter also needs to be disabled in streaming mode streaming tts can reduce perceived latency but may introduce audio playback issues on unstable network connections splitter controls text chunking behavior for long form responses when enabled, responses are split into smaller segments for processing type boolean default false operating modes all modes text splitter splitter needs to be disabled when using streaming mode, and it should be enabled with the legacy synthesizer this will happen automatically when the videostreaming parameter is toggled security & embedding parameters allowedorigins configures cross origin resource sharing (cors) settings to

notes parameter updates most parameters can be updated multiple times after digital human creation using the /head/update endpoint you can modify multiple parameters in a single request operation mode immutability the operationmode cannot be changed after creation plan your operation mode carefully based on your use case requirements voice specific settings parameters like customwords are voice specific and may need adjustment when changing voices voice provider and voice id when changing voice provider make sure to also include a specific voice id bearer token required all api requests require a valid bearer token in the authorization header
